OLED mini projector prototype for mobile phones using a series of lenses developed

Researchers at the Fraunhofer Institute — partnered with project HYPOLED — have created an OLED mini projector prototype for mobile phones. Unlike many previous iterations of similar technologies, this new prototype doesn’t need an additional illumination system, instead relying on a lens system to project images produced by an OLED onto a screen or wall — making it both smaller and more energy efficient. The prototype currently displays a monochrome image with a brightness of 10,000 candelas per square meter, and color images with a brightness of about half of that. The lenses are also made of glass at this point, though cheaper and simpler plastic ones are in the works. No word on when we might see these prototypes hitting the streets in actual projector phones, though.

Europe Gets Universal Cellphone Charger in 2010

microusb
The movement toward adopting a universal cellphone charger — that is, one type of charger that’s compatible with all cellphones — is becoming a reality in Europe as soon as 2010.

Several major mobile manufacturers, including Nokia, Apple and Research in Motion, have signed up for the universal charger initiative led by the Group Special Mobile Association (GSMA), according to Reuters.

GSMA announced the initiative in February with a goal of pushing manufacturers to use Micro USB as the charging standard for all cellphones by 2012. Europe is getting a head start, as several manufacturers have agreed to implement Micro USB in their phones next year.

The 10 cellphone manufacturers beginning Micro USB adoption in Europe are Apple, Nokia, Sony Ericsson, Motorola, LG , NEC, Qualcomm, Research In Motion, Samsung and Texas Instruments.

The goal of the universal charging solution is to address the environmental impact of cellphone chargers. By having one charger for every phone, cellphone manufacturers will be able to offer chargers as an option rather than an included accessory. The GSMA estimates a universal charger will cut down on the energy and materials required to produce charger by 51,000 tons, reducing the overall amount of chargers produced by 50 percent. This would also decrease the amount of waste created by discarded, useless cellphone chargers.

We’re wondering what Apple will do for its iPhone. Will the company remove its USB dock connector and replace it with Micro USB, rendering the iPhone incompatible with available accessories such as speakers and docks? Or will Apple keep the dock connector and add the Micro USB port? The latter option would likely satisfy customers who own accessories, but it would not enable Apple to cut down on the number of USB dock connector cords produced.

Jailbreak and Unlock iPhone 3.0

There’s no need to be intimidated. I’m here to hold your hand every step of the way while you jailbreak or unlock your original iPhone, iPhone 3G or iPod Touch, and it’s really not much hassle at all. (One Page)




Step 1
Let’s check to see if jailbreaking or unlocking an iPhone makes sense for you by explaining what they actually mean: Jailbreaking allows you to load non-iTunes, third-party apps like these onto the phone, at your own risk. Unlocking lets you use another company’s SIM card (for T-Mobile or international travel). That’s it. And if you don’t like it, you can restore the original Apple software any time using iTunes’ Restore button—we’ve done it plenty of times.

This guide is for the original iPhone, iPhone 3G and iPod Touch running the new iPhone 3.0 firmware. If you own a 3GS, you’ll need to wait since it hasn’t been hacked quite yet. But if you’re ready to hack your iPhone, grab your Mac or PC, iPhone and the USB adapter cable. Let’s do this. (Oh, and go to THIS LINK if you’d rather see all of the instructions on one big page.)



Step 2
Even if all you want to do is unlock the phone, you need to jailbreak it first, and that requires redsn0w, a Mac/PC jailbreaking program. Download the official redsnow torrent files HERE, then download redsn0w via your Bittorrent client of choice. Make sure you’ve backed up your iPhone to your computer before moving forward. That creates a data restore point in case you want to ditch the jailbreak apps. Done? OK. Last, if you’re moving your phone to T-Mobile, disable 3G before going on to the next step.

Step 3
Redsn0w works by patching the iPhone firmware file on your computer, then loading it onto your iPhone without using iTunes. So open redsn0w. Follow its instructions to select your .ipsw (iPhone firmware) file. On Macs, you can find the file at Home Folder/Library/iTunes/iPhone Software Updates. Or just download a new one from HERE. Once you’ve found your .ipsw, move on.


The image associated with this post is best viewed using a browser.
Step 4
Begin patching, but keep in mind this one setting: Redsn0w will ask if you want to install Cydia or Icy or Both. (These are apps that can load programs on jailbroken phones and will be needed to unlock the phone later.) JUST INSTALL CYDIA, NOT BOTH, OR ERRORS ARE PRONE TO ARISE LATER. TRUST ME. Once the .ipsw file is patched, make sure to plug in your iPhone then turn it off while still plugged. When you see the screen “Click NEXT when your iPhone is both OFF and plugged in…” go on to the next step.


The image associated with this post is best viewed using a browser.
Step 5
Now you need to put your phone into DFU mode to load the patched firmware. You’ll hold the top power button for two seconds, then hold the Home button with it for 10. Then you’ll release the top button and just hold Home for 30 or so. It’s not as hard as it sounds, and if you mess up you can just try again, but you need to pay attention, so make sure you’re holding your phone and watching the computer screen when you hit “next.” Redsn0w will guide you through the pattern of holding the top and home buttons in timed succession. If you’re successful, redsn0w will inform you that your phone is being jailbroken and you can stop holding the Home button. If you’re not, redsn0w will reset the process and you’ll probably need to manually restart your iPhone.

Step 6
Wait as the jailbroken firmware loads onto your iPhone. (You’ll see a disk drive on the phone’s screen, then this cute pineapple graphic as it installs.) After a few minutes, the phone will reboot just as it does with official firmware. Congratulations, your phone is jailbroken! Most of you are done—just load Cydia (which is now an app on your iPhone) and search for apps you’d like to install. Others need to continue this tutorial for the unlock.

Step 7
If you want to unlock your original or 3G iPhone so it can take a T-Mobile or international SIM, follow these next steps. You’re done with your computer, so make sure your iPhone is on a Wi-Fi connection. We’re going to use Cydia to download and install ultrasn0w, which unlocks your iPhone.


The image associated with this post is best viewed using a browser.
Step 8
Cydia will first ask what kind of interface you’d like. I’m no hacker, so I chose the graphical view. Then Cydia will want to download at least 2 Essential Upgrades. Let it by choosing “complete upgrade.” If Cydia’s successful, you’ll see a bunch of install code and the option to “Close Cydia (Restart).” Hit that button. (Note: If you are getting errors in this step, it may be because you installed both Cydia and Icy. If you did that, restore your iPhone with official 3.0 firmware via iTunes and start the process over.)


The image associated with this post is best viewed using a browser.
Step 9
Reopen Cydia. Go to Manage -> Sources -> Edit – > Add and then enter “repo666.ultrasn0w.com” in the text field. This should add ultrasn0w as a Cydia source so that you can download the ultrasn0w software. Choose to return to Cydia and then click “Done”.


The image associated with this post is best viewed using a browser.
Step 10
Click the repo666.ultrasn0w.com listing under your Sources. Click repo666.ultrasn0w.com again at the next screen (redundant, we know). Then click Install. You’ll see a black screen with some text and, after a few seconds, it should read “Complete”. Reboot your phone with your new SIM.

Congratulations, your iPhone is unlocked! But if you’re having any type of problems (it’s not our fault!!) check out the Dev Team blog. Chances are that if you’ve encountered a particular issue, so has someone else.

Video: iPhone 3GS gets professional shoulder mount, we giggle

So, the first time we watched this Macbreak video, we thought to ourselves, “now, this is downright silly” but the second time? Well… we probably won’t be investing $300 in a pro Red Rocks Micro shoulder mount for any iPhone 3GSs anytime soon, but the video does demonstrate what we all already knew: if you stabilize an even decent mobile phone cam, the results are better than if you don’t. Insane? Surely. Hit the second read link for the video.

Apple Giving $30 iTunes Credit For iPhone 3GS Activation Snafu

Following iPhone 3GS/AT&T activation delays that were in some cases 48 hours long, Apple has allegedly responded with a $30 “We’re sorry” gift that will be good at the iTunes Store on Monday.

Notification came by way of an email, which we’ve seen from Giz readers as well as around the Net this weekend:

Dear Apple Customer,

Thank you for your recent Apple Store order. We appreciate your patience and apologize for the inconvenience caused by the delay in your iPhone activation.

We are still resolving the issue that was encountered while activating your iPhone with AT&T. Unfortunately, due to system issues and continued high activation volumes, this could take us up to an additional 48 hours to complete.

On Monday, you’ll receive an email from Apple with an iTunes Store credit in the amount of $30. We hope you will enjoy this gift and accept our sincere apologies for the inconvenience this delay has caused.

Thank you for choosing Apple.

Sincerely,
Apple Online Store Team

So, on the one hand you’re going to get $30 in free stuff from Apple on Monday. On the other hand you could be one of the unlucky saps on the far end of this issue who’s about to experience 96 hours without a phone. Worse still, your new iPhone 3GS could be singing to you right now too. [Thanks, Patrick, et al]

Keepin’ it real fake, part CCXVIII: iPhome 3G for the wim!

Sure, we’ve seen plenty of iPhone clones in our day, but we’ll say this: this is the clome to beat all clomes. It really takes the KIRF standard up a notch, running the best fake OS X we’ve seen to date. This one’s identity is less confused than many of the knockoffs we usually see, and if you’re lucky enough to get your hands on one of these 4GB having-babies… well, you just might be able to convince your grandma that it’s the iPhone 3G S. Video is after the break.

Maria Sharapova models Bluetooth-enabled Sony Ericsson prototype dress

Sony Ericsson’s official spokesperson, Maria Sharapova, was on hand recently to unveil a student-designed prototype of a Bluetooth-enabled dress. The iridescent scales that run up one side of the dress move and light up when the phone rings, enabling its owner to know about calls even in noisy places (so says the dress’s maker, Georgie Davies). Yes, it’s just a prototype for now, but it’s a pretty cute dress, so hopefully we’ll see these hit the streets at some point in the (nearish) future.

iPhone 3GS Review

What’s the point in buying a new iPhone if it looks exactly like the old one? Because once you start using it, the speed of the iPhone 3GS will amaze you.

There’s a reason why Apple called this the iPhone 3GS for Speed and not the 3GC for “compass” or 3GV for “video recording.” Speed is the central upgrade here, and probably is the single biggest reason you would upgrade to a 3GS from a 3G. And if you’re coming in as a virgin iPhone user, there’s definitely no question: The 3GS is worth an extra $100.

That declaration may be weird to most of us since we usually look for features, and not specs, when we’re evaluating phones—and iPhone 3GS doesn’t blow us out in the feature department. Instead, it’s like getting a bigger TV or a faster car. Your old machine works just fine, but once you’ve tried the new one for a week, you’ll never want to go back, even if it costs you a little extra.

Like we said, from the outside the 3GS is exactly the same as the 3G. It’s slightly heavier and has glossy text on the back, but if Steve Jobs whipped one out in public before it was announced, you wouldn’t have been able to tell the difference.

By holding the 3GS next to the 3G, you’ll notice that the screen is slightly more reflective because of the new fingerprint resistant oleophobic coating. It even has a little bit of a rainbow effect if you reflect a monitor with it. Surprisingly, the coating actually works in preventing a good deal of fingerprints and face grease, and it allows the phone to still be smooth and usable even if there are fingerprints on the surface.

The shot above illustrates the fact. The two phones may look similar in how much finger and face grease are on the screen, but the iPhone 3GS is still usable and doesn’t have the problem of “sticking” in certain areas that are slightly greasier. It’s also easier to clean just by wiping on your shirt. The glass treatment won’t eliminate smudging from your bodily secretions altogether, but it’s a very useful improvement for something you’re touching all the time.

The 3GS display is ever-so-slightly warmer than the 3G’s, having a yellow/orangish tint when viewed side by side. If you remember, the 3G’s screen was also warmer than the 2G’s. It’s not distracting in any way, and the warm screen is slightly easier on your eyes even if the brightness is bumped up high.


The video really shows how fast the iPhone 3GS is. Safari, Email, Camera all load noticeably faster than on the iPhone 3G (both running 3.0 software). Even booting the phone takes about half the time. Apps with long load times, like Sims 3, Oregon Trail or Metal Gear Touch all show how much faster you get up and running on the new device. Seriously, everything is faster. It’s exactly the same experience as switching from a two- or three-year-old computer to something brand new. Your apps all look the same, but they load and run much more smoothly. Even if you’re doing the same things on both machines, the new machine is that much better to work on.

What does this speed increase mean for future iPhone apps and games? With the iPhone 3GS running on a 600MHz CPU with 256MB RAM (up from 400MHz and 128MB), there’s a much higher performance ceiling for apps to hit. The OpenGL ES 2.0 graphics standard that’s now supported paves the way for an impressive visual boost. Hubert (a former Nvidia developer) from Ubergizmo says it’s somewhere along the lines of going from Half Life 1 to Half Life 2, which is essentially going up a console generation. Gamers should pay attention.

Like we said before, the iPhone 3G will still run most of the games for the near future. That 40 million unit potential market of iPhone/iPod Touch devices is too big to just ignore and put out an app just for 3GS phones, so your old phone will still be able to keep up. But developers are like alcoholics. If you put more system resources in front of them, they can’t help but use all of it just because they can. Also, they drink a lot.

Apple hates to emphasize specs in products like the iPhone 3GS, but even they couldn’t resist bragging about the speed boost. That S is there for a reason.

The 3GS also has a 3-megapixel camera, adding auto focus and video recording. You even get an interface that lets you tap on a section of the screen that you want to focus on and the phone will automatically adjust the focus to that point in space.

By tapping on the screen and activating the auto-everything—not just auto focus but improved auto exposure and auto white balance—you’re gaining the ability to control more of what your shots look like. It’s most obvious in macro shots where the subject is only a few inches away (above). Those two photos were shot from the exact same distance in the exact same lighting. You can also see in the gallery below that the 3GS is slightly better in low-light conditions (something the 3G was no good at), as well as having better overall auto white balance.

I wouldn’t say it’s a mindblowing revolutionary step for the iPhone camera, but it’s definitely more than just shoving in more megapixels and leaving it at that.

The video quality, on the other hand, is pretty good for a cellphone. Apple claims up to 30 frames per second, and as this video of an HD recording of SNL shows, it comes pretty damn close. Even if it’s not quite 30FPS at all times, the video is smooth as hell. Recording still isn’t great in low light since it’s a physical limitation of cameras in general, but at least it’s fluid. The tap-to-focus (and re-expose) feature also carries over to video, which you can use to “aim” your camera at a part of the scene.

You’ll also want to use the quick trimming feature before you upload your videos directly to YouTube to cut out the excess at the front and back of your clips. The quick trim is just like trimming a clip in iMovie, with the yellow draggable borders. Apple says that the 3G doesn’t have video because the old processor isn’t capable of handling it, and after taking the 30FPS videos on the 3GS, we can believe that they didn’t want to settle for just 15FPS videos.

Data hogs will also be happy about the increased 7.2Mbps data speeds the 3GS can achieve. We used the Speedtest app in the App Store and over multiple days and multiple times (early, mid-day and late at night), clocked the 3GS at an average of 1568Kbps, whereas the 3G only measured 1165Kbps. Their uploads were relatively equal, at 226Kbps (3GS) and 209Kbps (3G), but there was a noticeable difference in latency with the 3GS pulling ahead at 174ms to the 3G’s 231ms. Although on average the 3GS scored about 50% higher than the 3G, occasionally, in individual runs, it could have ranged anywhere from twice as fast to about the same speeds.

The speed boost for downloads is interesting, seeing as AT&T hasn’t even begun to really roll out their 7.2 HSPA in very many places yet. Since we’re testing this before the actual 3GS release date, we’ll see how much loads of 3GS users will impact overall speeds, and we’ll see how fast the 3GS speeds increase once AT&T has the infrastructure to support it.

If you’re talking practical use scenarios right now, the increased network speeds and the increased processing speeds help to cut down wait times for both the email and Safari and whatever other app you use that grabs a bunch of data often. Even if you’re on Wi-Fi, the fact that there’s a faster processor on board mean that you’re going to be done faster than on the 3G.

The compass app, along with the magnetometer, is great at pointing you somewhere in the general direction of North. It also doesn’t matter which way you’re holding the phone—either parallel or perpendicular to the ground—the arrow and numbers will still more or less give you a sense of where you’re facing.

As a bonus, if you hit the “find me” button in Google Maps a second time after it’s located your GPS position, it’ll re-orient your map to reflect the way you’re facing. It would have been extremely useful when I was on foot, lost in San Francisco trying catch the last train, not knowing which way was which since the street signs are so small and the blocks are so large. If I had this, I wouldn’t have to have gone a block in the wrong direction just to figure out I should have been heading the other way.

The compass may not sound like a great feature, but apps like Layar, an augmented reality browser, are now capable of running on the 3GS with the help of the magnetometer and GPS.

Nike+ support is something that I’ve been looking forward to for a long time—so much so that I even bought an iPod Touch 2G to use it. Well, it’s here, and it works. The app is exactly like the one on the 2G Touch, and enables you all the running features you’re accustomed to using on any other Nike+ device. What’s nice about using your phone when running is that you always have your phone with you, and if you have a stereo Bluetooth headset, you’ll be able to listen to music, run and answer a call if need be.

Voice control actually works. As long as you know the right commands, like “call” for calling someone on your contact list and “dial” if you want to dial a number. The accuracy is quite high, and the app can recognize what you’re saying as long as there’s not too much background noise. It’s also fairly smart. If you say “call Mike” and you have multiple Mikes in your list, the iPhone will say the names of all your Mikes and ask you to be more specific.

The song control works, but gets confused occasionally because bands have weird names that aren’t exactly English—they just share the same letters. The iPhone kept confusing “Phoenix” with “INXS” or “DMX”, for example, but managed to actually get commands like “pause music”, “who is this song by”, “previous track” “what song is playing?”, “shuffle” and “play more like this” correct. And if you’re worried about figuring out what to say to control your phone, just activate the Voice Control function and watch the screen; eventually the command you want will come floating by in the background.


What’s also surprising about the 3GS is that you wouldn’t expect battery life to be improved, but it is. Apple’s figures that measured improvement over the 3G in every category except 3G calling were more or less what we found in our own testing, which means you should be able to last the entire day on one charge with no problems. Plus, since the phone is faster, you’ll probably spend less time looking up directions or getting to a restaurant’s web page—which also saves battery.

The iPhone 3GS is not an insignificant step forward in the iPhone family. The Nike+ support, magnetometer (compass), video recording, voice command, better camera, better battery life and faster data network are all improvements nobody would call a step backwards. But the biggest day-to-day improvement over the 3G is undoubtedly the increased processing speed, which is why Apple called this phone the 3GS (with the S standing for super fast) in order to designate that it’s basically the 3G, but better.

3G users have the unfortunate question of asking themselves whether or not they want to spend the $399/$499 to upgrade to the 3GS right now. If you’re eligible to upgrade in July, August or September, AT&T’s letting you do so at the full subsidized $199/$299 price. If not, you’ll have to wait until your 18 months are up. It’s definitely a better phone, but AT&T’s plan of making early adopters wait another six months from now until they can get the standard $199/$299 price is frustrating, since we’ll already be halfway into the iPhone 3GS lifecycle. And by then, it’ll be worth waiting until June 2010 for a true revolutionary jump in iPhone design, instead of just an evolutionary improvement on the 3G.

Our first generation iPhone review verdict was to wait. Our iPhone 3G review gave the go-ahead to finally mount up. The only issue with the iPhone 3GS, if you already have the 3G, is that it’s not all that different of an experience.

Like I said in the Palm Pre review, I’m a bit bored of the iPhone look and feel. If you’re looking for something new, something different and something you’re not quite familiar with, there’s the Pre or the MyTouch 3G. But as a whole, the iPhone 3GS is the best all-around smartphone available. If you’re looking for a refined, augmented version of what you already know, a phone that, not for nothing, runs all the tens of thousands of apps on the App Store, choose the iPhone 3GS. [Apple]

It’s quite a bit faster than the 3G


Hardware additions like better camera, magnetometer (compass) and fingerprint-resistant screen are a nice touch


Same size and shape as the 3G, so your accessories will all still work

Smartphone Buyers Guide: The Best of the Best

As the dust settles from the last two weeks of mobile madness, one question remains unanswered: Which of the new generation of smartphones should you actually buy? We’ve collected everything you need to know.

We’ve selected the five phones that most feel like modern handsets to us—the iPhone 3G, iPhone 3G S, the Palm Pre, the HTC Magic (or, as we soon expect, the T-Mobile G2) and the BlackBerry Storm—and broken them down by hardware, software and cost. This is a guide in the strictest sense, meaning we aren’t declaring winners or losers, just giving you the information you need to make your own choice. So! On with the matrices. Phones’ hardware specs tend to dominate carriers’ marketing, but in many cases they just don’t mean much, with a few exceptions: screens, storage, graphics performance and input.

The iPhones and Pre hold a sizable advantage in the screen department, trumping the G2, which doesn’t have multitouch, and the Storm, which has an ill-conceived pseudo-multitouch clickscreen that left most reviewers at best underwhelmed, and at worst downright frustrated.

In terms of storage, our phones take two fundamentally different approaches. The iPhone and Pre include healthy amounts of nonremovable storage—in the case of the iPhone 3G S, up to 32GB—which makes sense: if we’re going to use our phones as they’re marketed (as multimedia devices), we need space. The G2, like the G1 before it, depends on a removable microSD card for file storage, since its inbuilt memory is measured in megabytes. So does the Storm. This is fine if the carrier bundles the handset with a capacious card; Verizon is good about this. T-Mobile, on the other hand, shipped the G1 with a pitifully small 1GB card, so we’ll just have to hope they’re more generous with the G2.

Technical 3D ability is actually fairly uniform across this hardware, with the exception of the iPhone 3G S, which is, in this area, a next-gen product. Only Apple and HTC, though, give developers any meaningful kind of access to their handsets’ graphics accelerators, meaning the G2 and iPhones (particularly the bulked-up 3G S) will be the sole options for would-be gamers. And of the two platforms, iPhone OS has amassed plenty of serious gaming titles, while Android, let’s be honest, hasn’t.

The Pre is an obvious standout in that it has a hardware keyboard in addition to its touchscreen. The hardware QWERTY/onscreen keyboard debate is all about personal preference, so whether this is a boon or a burden is up to you. Typing on a screen is an acquired skill—but much more so on the Storm than the iPhone or G2.

Battery life would seem to be a valuable metric; it’s not. The differences in capacity and claimed endurance don’t really matter much, since realistically, they all need to be charged nightly.

Note: the Storm is due a minor hardware refresh, possibly quite soon. The main change, it’s been rumored, is a different touchscreen.
The greatest hardware in the world couldn’t save a phone with shitty software, and your handset’s OS is the single largest determining factor in how you’ll enjoy your phone. We’ve explored the differences between the major smartphone platforms at length here, and there’s no point getting too far into the specific differences right now.

To summarize: iPhone OS claims advantages in ease of use, its burgeoning App Store, and a respectable core feature set, but falters on multitasking and its lack of ability to install unsanctioned apps. The Pre’s WebOS is extremely slick and friendly to multitasking, but its App Catalog is light on content, and its development SDK is somewhat restrictive. Android and BlackBerry OS are both more laissez-faire, letting users install apps from whatever source they choose. Neither of their app stores is spectacular, but Android’s is markedly less anemic. More on app stores here.

Carrier preferences will often override prices, but here they are anyway. The Pre and G2 are the most economic options, and the Storm roughly ties the 3G S as the most expensive. (It’s easy to underestimate how much a small monthly cost difference can add up over two years.) But again, carrier loyalty (or more likely, disloyalty) and coverage quality is as important as cost. If Sprint’s killing your Pre buzz, it could be worth waiting until next year, when Verizon is rumored to pick it up. Likewise, if T-Mobile coverage in your area is patchy, don’t worry: by the time T-Mobile actually offers the G2, we’ll probably have at least another functionally identical handset lined up for release elsewhere.

So there you have it: everything you need to know about the latest crop of consumer smartphones. Go forth, and be gouged.
