Hasta La Gadget!

We heard from 9 to 5 Mac that Apple was due to begin selling a contract-free variant of the iPhone in the near future “at list price.” And guess what happened when we inquired to an Apple store? That’s right folks — you can now pick one up for $499 (3G), $599, or $699 (3GS). We’ve confirmed this info at no less than five stores, so you should be hearing the same message at your local Appletorium. Given the current unfriendly climate between Apple and Google, this could be seen as nasty jab, though the devices are still carrier-locked to AT&T, so you’re not being given much freedom… and it’s certainly not much of a statement. In many parts of Europe (France and Poland, for example) you can pick up the carrier-unattached device (and we mean totally unlocked), but that doesn’t appear to be the case here.

Update: We’re getting mixed reports on the unlock status of these phones. One store says yes to the unlock, while others are saying they’re still AT&T-locked devices being sold off contract. We’re digging for more info on this now, so stay tuned.

Update 2: It’s looking like those initial reports of unlocked devices are inaccurate. It sounds like these devices are still locked to AT&T — so you’re just looking at an off contract pricing scheme. Which is also totally lame.

iTunes gifting has always been a nice, lazy way to wish a friend a happy birthday or holiday, but until now that feature has been exclusive to iTunes audio and video media. Now, Apple has added the ability to send iPhone apps as gifts.

After agreeing to the new iTunes Store terms and conditions, you’ll be able to select a “Gift This App” option from the pull-down menu next to an app’s price. From thereon, you can punch in the name and e-mail address of your desired recipient, along with a personal message, and iTunes will send him or her a redemption code to download the app.

It works the same way as gifting music or movies, which has been a popular feature in the iTunes Store. This is especially good news for iPhone developers, as the gifting feature can induce brand new iPhone owners to download their first paid app ever. Gifting might just work as a gateway drug that gets iPhone owners hooked on the addictive experience of paying for new apps and digital media in general, which would further stimulate the app economy.

A hat tip to Rana Sobhany, who first noted the change in her blog.

A new sensor technology promises to make cellphone cameras good enough to use for wedding photos.

InVisage Technologies, a Menlo Park, California, company, has developed an image sensor using quantum dots instead of silicon. The company claims its technology increases sensor performance by more than four times.

“We have all heard ‘Gee, I wish the camera on my iPhone was better,’” says InVisage’s President and CEO Jess Lee. “But the heart of the problem is in the heart of the camera, which is the sensor.”

Most cameras today used either a CCD (charged-couple device) sensor or a CMOS (complementary metal-oxide-semiconductor)-based sensor. The silicon in current image sensors has a light-absorbing efficiency of only about 50 percent, says Lee.

Reducing efficiency still further are the layers of copper or aluminum circuitry laid on top of the silicon. The metal blocks the light, so only a fraction of a sensor’s silicon is exposed to light.

Replacing silicon with quantum dots could change all that. A quantum dot is a nanocrystal made of a special class of semiconductors. It allows manufacturers to have a very high degree of control over its conductive properties, and is about 90 percent efficient at absorbing light, according to Lee.

The quantum dots are usually suspended in fluid. InVisage takes a vial of these and spins it onto a layer of silicon, then adds the required metal circuitry to create a new type of sensor that it is calling QuantumFilm.

In addition to the increased sensitivity, InVisage’s technology allows the metal circuits to be placed underneath the quantum film, where they don’t block the light.

“This is entirely different from the type of image sensors that we have right now,” says Tom Hausken, director with market research firm Strategies Unlimited. “Usually you see incremental improvements in sensor design, but these guys have made a significant change in the process.”

Quantum dots can be made from silicon, tellurides or sulphides. InVisage won’t reveal exactly which material it is using.

As opposed to silicon’s indirect band gap, quantum dots have a direct band gap. Lee says Invisage can tune the Dots’ band gap much more efficiently than silicon so it is more sensitive to visible light, ultraviolet and even infrared waves.

In the last few years, manufacturers have been touting megapixels as the measure of a camera’s prowess. But the true measure of picture quality is not as much in the megapixels but in the size of the sensor used in the device.

To capture the light, imaging sensors need to have as much area as possible. Powerful DSLR cameras have an imaging sensor that’s about a third of the size of a business card, while camera phones sport sensors that are only about a quarter inch wide (see top photo). Smaller sensors mean less light sensitivity for each pixel on the sensor, and that translates into lower-quality images.

Quantum dot-based sensors won’t be more expensive than traditional CMOS-based sensors, promises Lee. InVisage says it will have samples ready for phone manufacturers by the end of the year and the sensors could be in phones by mid next-year.

Though quantum dots are commercially produced by other manufacturers, they have never been used on image sensors before, says Hausken.

“Mostly people have looked to use it in displays, solar cells and as identification markers,” he says. “So we will have to see how effective and reliable it is as a sensor.”

The iPhone’s iteration of Google Maps has been shown up time and time again by Google Maps Navigation on Android, but a quirk this big just has to be linked to some Skyhook database issue. According to a new report coming from the LA area, select iPhone users in Southbay cities near Los Angeles are seeing their GPS software linked to Boulder, Colorado, and the issue has been going on for around a week now. What’s curious is that the erroneous positioning affects other third-party iPhone GPS apps as well, and an ABC report notes that a “spokesperson at AT&T said the problem is with Apple.” Pass the blame much, AT&T? So, have any of you LA-based iPhoners found yourself navigating to Folsom Stadium when trying to find your way to Rodeo Drive?

Your existing iPhone (yeah, even the original) can surf the information superhighway at 4G speeds. Today. Who knew, right? Sprint’s Overdrive — which creates a WiFi hotspot that enables nearby devices to cruise on Clear’s 4G (or 3G, if you’re not in a 4G locale) network — can theoretically enable any WiFi-capable phone to surf on WiMAX, but Sprint’s taking a pretty bold approach by actually touting the feature in a new spot. Befuddled? Hop on past the break and mash play. Too bad this is about as close the iPhone will ever get to Sprint’s shelves…
