Hasta La Gadget!

Push. It’s not just a verb that sends people careening down a flight of stairs. It’s also not just for guys in suits diddling on BlackBerrys. You hear it featured on new iPhone apps every week. So, what is it?

Well, push describes a lot of things. Push is simply an action. Versus, say, pulling. Maybe that’s horribly abstract, so try this: If information shows up on your phone or neural implant or messaging program without you (or your wares) asking for it—that’s push. The info is pushed to you, versus you pulling it from the source. There are tons of ways push can be (and is) used.

Email’s a pretty good starting point for grasping the difference between push and the other stuff. You probably know good ol’ POP3—you log into your mail server and pull down new messages. Maybe it’s on a frequent schedule, so it feels automatic, even instant, but you’re still reaching out to the mail server every time to check and see if there’s new mail to download.

IMAP is a little fancier than POP, where all of your folders and email are the same on all of your computers, phones and other gadgets, and any change you make on one shows up on the other, since it’s all happening on a remote server somewhere. But with the standard setup, it’s still the same deal—your mail program has to log in, see what’s new, and pull it down. IMAP does have a pretty neat trick though, an optional feature called IMAP IDLE, that does push pretty well—it’s what the Palm Pre uses for Gmail, for instance. Essentially, with IMAP IDLE, the mail server can tell whatever mail app that you’ve got new messages waiting, without you (or your app) hammering the refresh button over and over. When the app knows there’s new messages, it connects and pulls them down, so it gives you just about the speed of push, without matching the precise mechanism.

While different systems do things differently (obvs), what true push services have in common is that they generally insert a middleman between you and the information source.

RIM’s setup for the BlackBerry is probably the most sophisticated. When your BlackBerry registers with the carrier (which has to support BlackBerry), the details are handed to RIM’s network operating center, so the NOC knows where to send your mail. The NOC watches your mail server, keeps tabs on the phone’s location, and pushes email through to your phone whenever you get new stuff.

What makes it push is that your phone’s not actually polling a server for new messages to pull—it only receives them when they hit your inbox, and are then pushed to your phone by RIM’s servers. This means you save a lot of battery life that’d be wasted by making the phone constantly hit the servers for updates. The flipside is that when RIM’s servers blow up, you don’t get email, since it’s all routed through their system—hence the other panic that grips dudes in suits once every few months lately.

The other biggie is Microsoft, who has Direct Push, part of Exchange’s ActiveSync. It’s architected a little bit differently, so it doesn’t need the precise kind of data about where your phone is that RIM’s NOCs do: The phone or whatever you’ve got sends an HTTPS with a long lifespan to the Exchange server—if new mail arrives before it dies, the Exchange tells your device there’s new stuff, so it should start a sync. After it syncs, the device sends out another long HTTPS request, starting it all over again.

Apple’s weak-sauce substitute for multitasking works pretty similarly: The developer has something its wants to send an iPhone, when its application isn’t actually running, like an IM. It sends the notification to Apple’s push servers, which send the notification to the phone through a “persistent IP connection” the phone maintains with the servers. This connection, which is only maintained when push notifications are turned on, is needed to locate the phone, but still doesn’t draw as much power as constantly pinging the mail server.

Of course, those aren’t the only push systems around, and it’s only getting more and more important as stuff gets shifted to the cloud. We haven’t mentioned Android and Google Chrome, but both utilize push (or will) in different ways. Suffice it to say, Google Sync will soon be a major player in this game. But basically, all kinds of different data can be pushed—calendars, contacts, browser data, hell, even IM is a kind of push—and they all work more or less the same broad way. Just don’t ask us why there isn’t push Gmail on the iPhone yet.

The App Store approval process has always been mysterious, slightly ridiculous and mildly infuriating. But with the summary execution of Google Latitude as well as every Google Voice app, it’s finally gone too far.

Until this past week, Google’s been the most privileged developer for the iPhone outside of Apple itself. I mean, Google Maps and YouTube come baked into the phone. Hell, Google even gave the iPhone voice search—a more powerful version, no less—before it delivered the feature to its own OS, very obviously using private APIs that would’ve likely resulted in a swift kick in the ass for any other developer.

Yet here we are, Apple has rejected not one, but two Google apps that would deliver major new features to the iPhone, for reasons that are so obviously tripe it’s insulting to even our non-exceptional intelligence. A Google Latitude app would confuse us? Really? Because it would “use Google to serve maps tiles”? Wait. Isn’t one of iPhone 3.0‘s major new features that it can use Google Maps inside of other applications? So like every app can use Google to serve maps tiles. I admit, though, Latitude is a really big word. What does it even mean? That is pretty confusing. Maybe they should call it, like, Google Stalker.

What happened with Google Voice is worse. Google didn’t elaborate on the reason Apple gave for rejecting its official Google Voice app six weeks ago—and presumably, Google had more success wringing it out of Apple than most developers. Hours before Google broke the news, the developer of GV Mobile—a solid third-party app for Google Voice—said that it was being pulled from the App Store for “duplicating iPhone features.” Then every other Google Voice application was silently killed too. Even though, reportedly, Apple’s Phil Schiller personally apologized when GV Mobile initially ran into problems getting approved months ago, and it’d been sitting pretty in the store since then. Oh, and there are tons of other apps that duplicate the functions of dialing and sending text messages.

John Gruber at Daring Fireball says Google Voice was nuked by AT&T, “it’s that simple.” It’s not the first time AT&T’s put a hit on apps: NetShare, the tethering app was yanked (though it clearly never should’ve been approved in the first place), and Skype and SlingPlayer streaming were crippled so that they only worked over Wi-Fi. The difference between those situations and this one is that in those cases, there was, at least nominally, a greater good for users: Limiting those apps protected people from the possibility of AT&T’s fragile, already busted-ass network completely collapsing under the weight of millions of phones streaming tons of data. And, you can still actually use Skype and Sling apps, albeit in a slightly constrained manner.

Google Voice, on the other hand, poses no such mortal danger to the network. It only uses a tiny bit of data at the very beginning of a call to set it up, and text messages sent through the service would be infinitesimally small scraps of data (not to mention, there are other immensely popular apps that already send text messages as data). You still use your AT&T voice minutes when you’re on a call using Google Voice. And, for whatever reason, AT&T’s fear is about Google Voice on the iPhone, since the app is available for BlackBerry on their network.

The situation crystallizes our worst fears about Apple’s dictatorial App Store. Users aren’t being protected from bad things or from themselves here. Even though it seemed ridiculous to us, when apps with objectionable content were blocked or booted before the ratings system was in place, it was in the interest of some paradoxically lazy but over-protective parent somewhere out there. But the only thing being guarded is some ephemeral long-term interest of AT&T against the devaluation of phone numbers and the ability to easily use any phone at will. (FWIW, AT&T says “AT&T is not involved in the approval process, so we can’t speak to this issue.”) Not only is Apple hurting users in the service of AT&T by denying them innovative new features, they won’t even bother to come up with a good excuse. If they’re going to lie about it, they could at least make the rationale believable.

To truly get a sense of the chickenshittniess on Apple’s part, Just read this account of the conversation VoiceCentral’s developer had with Apple when they were told their app was going to be pulled from the store. It’d be hilarious if it didn’t mean a developer got screwed.

It’s obvious Google’s not happy about it either—and not just because Google exec Marissa Mayer’s deleted tweet pointing to a satire piece about Google deleting Apple from its search results, since it “duplicates a lot of the functionality of other sites.” If everything was copacetic Google wouldn’t tell the world Apple shut down their applications. (And if the alternative web apps were all that great, Google wouldn’t make native apps to begin with.) Whatever the causes, there is now definitely a rift between Apple and Google.

It’s a sobering reminder of what Apple’s total control over the iPhone platform really means. For the first time, it’s denying people exciting new features and possibilities, without even a semblance of benefit or concern for users. Maybe it’s a catfight with Google. Maybe AT&T finally found a clause in its contract that didn’t make them Apple’s bitch. Either way, it’s just depressing.

A year after we said we still need the iPhone app black market, nothing’s changed. To wit, GV Mobile’s available on Cydia right now. We know the App Store is Apple’s exclusive domain, and playing in their space has its tradeoffs, but the implicit trust is that whatever Apple does that might seem ridiculous or weird, it’s ultimately trying to create a better experience for users. That’s just not the case here, taking the App Store approval process beyond cryptic and infuriating into something that’s actually toxic for users. Since it’s crossed that line, our App Disapproval Watch starts now—it ends when Apple finally cuts this crap out.

Now we know why Google Voice apps were only released for BlackBerry and Android. Apple rejected Google’s official Google Voice app when it was submitted for approval six weeks ago. What. The. Shit.

Here’s the quote from the Google spokesperson to TechCrunch:

“We work hard to bring Google applications to a number of mobile platforms, including the iPhone. Apple did not approve the Google Voice application we submitted six weeks ago to the Apple App Store. We will continue to work to bring our services to iPhone users – for example, by taking advantage of advances in mobile browsers.”

This news comes on the heels of Sean Kovacs’ GV Mobile Google Voice app being pulled from the store for “duplicating features.” Even though, TechCrunch relates, Phil Schiller himself personally approved GV Mobile and called Kovacs to apologize when its initial approval was delayed months ago.

TechCrunch suspects, probably correctly, that apps for Google Voice are being rejected at least in part through AT&T’s influence, since Google Voice lets you send free text messages and delivers cut-rate international calls—on top of making phone numbers even more meaningless—making it scary to AT&T in way like Skype VoIP over 3G. Either way, it seems obvious the Google Voice service is being targeted for extinction, at least as a native app on the iPhone.

Google plans to take the same route it was forced to take with Latitude on the iPhone—web app land. It’s an interesting switch for Google and Apple on the app front, actually. Google was noted for getting away with using private APIs in its Google Mobile app to make the voice search command work. Now Apple’s rejected two of its major apps in a row, in a way validating Google’s belief that web apps are the future anyway.

It seems somewhat silly, and a bit of a reach, to insinuate the rejections are signs of brewing hostilities between Apple and Google, but you have to figure if there weren’t any behind the rejections, they’ve at least got to be causing some anxiety by now.

Whatever the reasons, it sucks, and as Jason Kincaid says, what’s really troubling about this rejection is that it appears that “Apple is now actively stifling innovation.” And the whole black box app approval process doesn’t exactly alleviate that sinking feeling either. After all, if Google doesn’t stand a chance, how does anybody else? [TechCrunch]

In a very special late night edition of your weekly iPhone apptacular: Apps that make things that are already good—FM radio, video games, shopping, spouses, the city you live in—a little bit better.

Priceless Picks: Don’t let the advertising-crap-app appearance of Priceless Picks turn you off—this free download, branded all over with Mastercard, is great. It combines loads of data collected from a number of sources, including user submissions and Amazon’s Mechanical Turk army, to give wide-ranging recommendations for things to do, eat, drink or experience wherever you happen to be. There are other apps that do similar things, yes, but the dataset on this one already seems strong, the scope—not just restaurants, not just a particular company’s establishments—is healthy, and the 3D map presentation is fantastically cool, and surprisingly smooth.

Griffin iFM Radio Browser: A lot of people will download this assuming it’s a streaming radio app—it’s something else entirely, and actually quite exciting: iFM polls your location to come up with a list of local terrestrial radio stations, providing you with access to song titles, album art, artist info and purchase links for whatever’s playing on your FM station of choice. Think of it as augmented radio.

It’s also one of the earliest examples of accessory integration for OS 3.0, featuring a software interface for Griffin’s Navigate inline iPod remote, which has a built-in radio. Free. (The app, not the accessory. Sorry.)

Snore Patrol: Leave this app running overnight and it’ll provide a decibel readout of whatever weird nostril/sinus/lung business goes down in the duration. The idea is to present a snoring partner with graphical proof of their terrible flaw, which will in turn guilt them into doing something about it. It’s funny, but the pink interface and lady-oriented marketing is disheartening. Women snore too! MUST WE MEN SUFFER IN SILENCE? Your gynocentric passive aggressiveness: Free.

Squash the Street : If the economy’s got you down, and you’re vaguely upset about some fatcats on Wall Street, or at your banks, or something, why not direct a little bit of your pent-up aggression and/or depression into your iPhone? That’s what Squash the Street is for: Pure, possibly misguided venting. Neat 3D-ish graphics give this ultra-timely voodoo doll a bit of longevity. A dollar.

Cyclops: Barcode scanning apps are a no-brainer for modern smartphones: just snap a picture of a product’s label, and they’ll pull down a plethora of information. That’s exactly what Cyclops does. It’s not the first, but it’s the first designed around the iPhone 3GS’s new camera, which has good enough macro skills to make such an app truly useful. Free. [Via TUAW]

iMetal: There are many rules by which app developers live, some written, some not. One of the most powerful is the mandate that no hardware feature on any version of the iPhone shall go unused, or perhaps more accurately, unexploited. The iPhone 3GS utilizes a magnetometer for its compass, meaning that it can detect when certain metals are nearby, and that someone could theoretically make an app that acts as a sort of makeshift metal detector. And since nothing stays theoretical for more than a week in the App Store, someone has: it’s called iMetal, and it’ll tell you when you’re iPhone is next to a giant piece or iron, or hovering somewhere near a neodymium magnet. As an actual metal detector, it’s basically useless; as a party trick, it’s pretty neat. A dollar.

The Typography Manual: To most, this app will seem esoteric, or at worst, plain boring. To type nerds, however, this is like kerned, serifed manna from heaven. As its name implies, it’s something of a typography primer and history lesson, but on top of that, it’s a visual glossary, a collection of clever type tools, a directory of keyboard combinations for special symbols, and quite a bit more. Five dollars.

World of Warcraft Mobile Armory: Anyone who doesn’t play WoW won’t know what this is, and doesn’t need to. Anyone who does can download it for free.

For the iPhone 3GS, for which the new Pocket Universe is designed, you get full-on astronomical augmented reality. Using location services, accelerometer data and the 3GS’s compass, Pocket Universe pseudo-overlays information about your stars, planets, constellations and general space things according to whatever you’re pointing at. Three dollars.

Loopt for iPod Touch: The Loopt iPhone app has been around as long as, well, iPhone apps. Since 2008, it’s earned its keep as one of the only useful friend-locating apps. Just about every mobile platform has a client, with one notable exception: the iPod Touch. That, along with Of course, Loopt isn’t quite the same without GPS, but Wi-Fi location will get you by in a bind. Still waiting for a proper 3.0 version though. Free.

The image associated with this post is best viewed using a browser.Seek ‘n Spell: iPhone games tend to be a lot like games for any other portable device, and rarely leverage some of the traditionally non-gaming capabilities of the handset. Part of this is because, until recently, the developer SDK was sort of limited. Most of it, I think, is because developers just haven’t been thinking hard enough.

Take this clever, if obvious, idea for a game: A map of wherever you are is overlaid with letters, which you and you teammates can collect by physically running to their icons. Your goal is to come up with words for points, Scrabble-style. It’s a very, very cool idea, and decidedly sweatier than your typical iPhone game. A buck.

The image associated with this post is best viewed using a browser.MSNBC: Hey, look, another news organization has a content app! Let’s talk about it! This one’s less about news than about catering to fans of the network, with an emphasis on video content as well as Twitter feeds from MSNBC personalities. It’s a bit hard on the eyes, and occasionally goes stuttery on you, but it works fine. Fun fact: according to the iTunes description, this iPhone app, being an MSNBC product, uses “Microsoft’s Advanced Technologies.” What this means, I have no idea. Free.

The image associated with this post is best viewed using a browser.Fluent News: If you could sense a lack of excitement about that MSNBC app, that was because of apps like Fluent. It’s far from the first multi-source news aggregator, but it’s one of the better ones. It behave like Google News, more or less, collecting important news from lots of sources and grouping it in a sensible way Why not just use Google News then, you might rudely interject? Well, for one, Fluent can cache news for offline reading, for plans, subways, caves, or wherever. It also prefetches longer articles, though I couldn’t really tell in my brief testing. Anyway, it’s free, so why not?

Skype: Another incremental update to another extremely popular app. This one gets an interface lift, but most importantly, two useful features for people who use Skype’s pay services: text messaging with SkypeOut credit (good for cheap international texts; bad for having no reply function), and Skype Voicemail support. Voicemail support is a bigger deal than it sounds: since receiving calls when you’re out is still pretty much out of the question, the voicemail access makes being out of touch a little less irritating. Still free.

The image associated with this post is best viewed using a browser.Air Sharing Pro: We’ve always been impressed with Air Sharing—it’s a solid file storage/viewing solution in its basic form. The Pro version, though, is a different animal entirely. First of all, it’s expensive: $10, to be exact. It’s also got expanded support for file storage services like, MobileMe, MyDisk, and Drop.io.

The main draw is that there are tons of new file functions: emailing, which is a huge help; direct printing, via OS X printer sharing; archiving abilities, including viewing archive contents without extracting. It’s a bit like a walled-in version of Finder, and the closest to a proper file browser you’re going to get on a non-jailbroken iPhone.
