Since the arrival of the Push Notifications feature in iPhone OS 3.0, all manner of apps have added support for it. Games, task management applications, you name it -- they're all more than happy to make your phone beep at you in the middle of the night and prompt your spouse to kindly insist that you silence that infernal device. Or so I've heard.

It seems like a no-brainer to me that this type of functionality would exist among the throngs of social networking applications. If the game where you flick the thing while the music is playing can tell me when I've got a new challenger from the Far East, why can't my favorite Twitter client let me know when I've got a new direct message? Sadly, most of the apps in the store (as far as I know) haven't implemented this functionality yet. I realize that it has some sporadic adoption, but certainly not the universal support that I personally expected.

Enter Boxcar [iTunes Link]. This little free app has existed in the store for months now and has received some very nice reviews, and for good reason. I've been a faithful user of this app for many moons and I find it pretty indispensable. Here's how it works:

When you install the app (which is free at the time of this writing), you can choose to enable a single service for notification -- Twitter, Facebook or an email account. It will poll the selected service at a short interval and send you a standard push notification message if there are any updates. In the case of Twitter, you can configure it to open one of several supported Twitter client apps. If you want to enable additional services, you can do so through the in-app purchase mechanism, and most options cost $.99US.

I'm a big fan of Boxcar and use it for Twitter and Facebook. It's one of those free applications that's actually worth more than what you're paying for it -- a quality that's becoming increasingly rare among free iPhone apps these days! Version 2.1 was just released a few days ago and includes several new features like support for Facebook Mail and better accessibility.

Pick up Boxcar now for free from the App Store.

I only follow a few sports teams, but for the teams I do follow, Sportacular (that's the iTunes link for the free version, and here's the paid version, sans ads) is definitely my app of choice. For nearly every professional sport you can think of, the app will track scores, plays, schedules, standings, and anything else you need to know about everything from NFL to college football to the English Premier League and the PGA.

Right after iPhone OS 3.0 came out, the developer added in push notifications, and now I've got push updates coming whenever the Cubs have a game starting and ending (or at least, when they did -- there's always next year) and whenever a Bears quarter ends. Sportacular even has a few social features happening -- you can make picks and discuss each game with other fans using your Facebook login, as well as read news and updates about each team in the games you check out.

The app was updated to version 1.6 last night, and the new features include better game pages for NFL and NCAA football, and option to manage and track your fantasy football team in conjunction with their fantasy football app on Facebook. The one bummer I have is that they don't have actual media of the games -- for that, you'll probably have to go for an official app. But especially as a free download (the ads are definitely non-intrusive), Sportacular is really impressive with everything it does to help you track your favorite sports and teams.

CNN chatted with our good friends at DLS about the news network's iPhone app (scheduled to hit an App Store near you very soon), and it actually sounds pretty premium: in-app video, breaking news live video streaming, a Coverflow-style way to browse news information, the ability to store news to read later, and social sharing through Facebook, Twitter, and the usual suspects. CNN even says they want to add more to the app in the future, including some iReport-style news delivery functions, so people with iPhones out in the world can send news in as quickly as possible.

Ok, CNN, we get it -- you care about this one. It does sound like they're making a major push in terms of making their content interactive on the iPhone, but on the other hand, maybe they're just trying to sell you on the "premium" price: $1.99, with (we're told) non-intrusive advertising included. Obviously, $2 is cheap, but on the other hand, especially with advertising both from the network itself and outside clients, the crankiest of App Store browsers will probably flinch at it a little bit. If you are interested, however, CNN would love to take your money: their app should be available in the App Store as soon as Apple lets it through.

There's a first time for everything: while the updated premium version of AOL Instant Messenger for the iPhone [iTunes link] was scheduled to arrive later this month, CNET reported that it actually went through the approval process early (no!) and as such it represents the first of the AIM clients to support the new AIM Lifestream multi-service status update capability.

If you check out the landing page for the service at lifestream.aim.com, you'll be able to update and monitor your posts and pictures on Delicious, Digg, YouTube, Flickr, Facebook, and Twitter alongside your AIM status (and with your AIM buddies in the mix). The Mac and Windows clients for the service are expected on 9/22; it's not known yet when the Lifestream goodness will make its way to the free & ad-supported AIM client for iPhone.

Although you can certainly handle multiple social services from several Mac apps (EventBox, Tweetdeck, MoodBlast), and the iPhone has multi-chat tools like Nimbuzz and Beejive, having the flow of statuses pouring in for AIM users will up the ante considerably. We'll keep an eye out for the official Lifestream launch next week.

Forgot to mention: Can we please, please have an AIM client for iPhone that supports group chat? If we're going to pony up $2.99 for the premium AOL client or even more for Beejive, it should have this bit of functionality, don't you think?

Mac-using Facebook fans are going to be happy to learn about Facebook's experimental Desktop Notifications app. Desktop Notifications sits in the menu bar, and pops up notifications (using Growl if you have it) when they occur. It also gives you quick access to your news feed, profile page, and quick ways to update your status or start a new Facebook email message.

There are two things about Desktop Notifications that are compelling, yet have nothing to do with the app itself. The first is the fact that it's a native Mac application, rather than yet another Facebook client written on Adobe Air. The second is that it was actually developed by Facebook themselves [Update] Thanks to Raul and Nate for pointing out in the comments that the application is marked as "not developed by Facebook", though one of the developers listed works for Facebook. It's unclear at this point how serious this project is; it's clearly marked as experimental, which is clearly becoming the post-Gmail way of denoting that something is beta.

In terms of raw functionality, Desktop Notifications is pretty barebones, since most of what it does is take you to a particular Facebook page. Personally I kind of like it that way. It's relatively light in terms of memory usage, and uses virtually no CPU cycles at all unless you are actively interacting with it, which is exactly what I want from a utility that is running all the time.

My one beef is that the built-in hotkey that pops up a status update dialog box conflicts with another utility on my system, and there is no way to modify it. Since Desktop Notifications is still in the experimental stage, that's a pretty small complaint.

[Update] Commenter Scott points out that there is a preference setting to change the hotkey.

Yeah, like everyone else, iTunes has fan page on Facebook. If you can stomach the process, you can even get 20 songs for free by becoming a fan. The process is a bit clunky, however, which seems to be par for the course on Facebook. First, you become a fan. Then, you'll need to allow the "Free On iTunes" app to get access to your profile (typical of a Facebook app, of course). Then, you click a link that says "redeem now" -- a link which took me to a blank page.

After digging back into the fan page again, I found that button again, and clicked it again. This time I got the right page, but iTunes never woke up (that is, the store link didn't work). Then I tried yet again to "redeem now" and voila! A page warning that I'd already done all this appeared. Luckily there was a redemption code on this page, and the "redeem now" button finally worked. I am now downloading iTunes 9, iPhone OS 3.1 and 20 songs by indie artists.

If you can suffer the mess that is Facebook, you can get some free tunes.

We're always trying new things around here, from apps to web services to hardware and all kinds of novel ways to do what we do. We also appreciate the fact that many of you read us via RSS or even the iPhone. To that end, here's a list of the many ways to enjoy TUAW in all its myriad forms. If you think we're missing something spectacular, let us know in the comments.

Heeeere's TUAW, in reverse order of no particular importance:

After a couple of weeks of waiting in the iTunes app store approval queue, the 3rd major update of the popular Facebook for iPhone [iTunes Link] application has been released. Joe Hewitt, the developer of the app, has been working on it for quite some time and submitted it for review on 8/16. If you're still seeing 2.5 in the app store, Joe suggests deleting the app from your phone and reinstalling it -- it will be 3.0.

The new version includes some of the most requested features including:

• Better news feed with direct links to comments
• Ability to "Like" posts
• RSVP to events
• Create/upload photos to albums
• Write/edit notes
• Customizable home screen
• Improved photo viewing with zoom
• Better notifications

Hewitt is already working on the next release, version 3.1, which is rumored to focus on adding Push Notifications.

Check out some shots of the app in action:

There's no shortage of Twitter apps in the App Store. Even more surprising is the number of GOOD apps that connect to the popular microblogging platform. I like each for a different reason: Tweetie has a clean user interface, TweetDeck offers multiple columns that sync with its desktop counterpart, and TwitterFon has ReadItLater integration. There are countless others that have unique features, and many of us end up with at least a couple on our iDevices.

But I have a new favorite, qTweeter, developed by the folks at Efiko Software. You won't find it in the App Store, though, because this app requires a jailbroken device. Multitasking isn't officially allowed (yet?) on the iPhone OS, yet qTweeter relies on this capability to perform its best trick.

Say you're checking the weather and want to tell everyone of the approaching hurricane. Normally, you would close your weather application, swipe through pages of apps, tap on and wait for your favorite Twitter client to open and load all of the tweets that you really don't care about right now, and finally type your warning to get the heck out of town. By the time you do all of that, the highway is going to be grid-locked with fleeing residents and you'll be stuck boarding up windows and sweeping up the debris!

Instead, you could have just "pulled" qTweeter down from the status bar, typed your tweet, and went back to the app still running in the background.

In fact, per the recent trend, you could have also posted that same message to your Facebook status with just a tap of a checkbox. It's a much quicker way to get your message out of your head and onto the Net, a fact that you'll appreciate as you get older and those thoughts become more fleeting.

I've been playing with the hyped-up Booyah Society app for about a week or so now, and I don't think my reaction is too singular: it's not all that great. The idea is certainly a good one: take your real-life achievements and turn them into a game, complete with points and an avatar, but in practice, it's not quite there yet. Achievements are honor-based, which means you can make as many or as few points as you want just by punching anything in, and while the avatar is pretty nifty, it doesn't seem like there's that much to do with the little guy besides spin him around until he gets sick. That's not to say that the potential isn't still there -- the app's "Booyah" recommendations can give you some interesting things to do if you need them, and if they ever get the app using some actual iPhone mechanics (how about traveling a certain distance according to the GPS or playing a certain song or sound into the microphone?), it could be really addictive. But they're not quite there yet, and while we don't have any info on how many downloads they've gotten, the App Store rating is less than impressive at two-and-a-half stars.

And they're not giving up yet -- they just announced a giveaway of up to $1000 over on Facebook. You'll have to log in to see it, but if you become a fan of their service and fill out a quick sweepstakes form, you're entered in to win a $500 Apple gift card for yourself, as well as a chance to give $500 to five more friends.

Sure, the contest is blatant promotion (and it might even just be a shot in the dark to try and grab a Facebook audience). But what will be interesting here is to watch and see what happens with the app -- these guys have a legendary game development background (coming from Blizzard Entertainment), and at least $4.5 million in VC financing already. Whether they sink or swim, they're making for a very interesting case study of big-time development on the iPhone.

It's an increasingly crowded category on the App Store: Social Networking. Like several other apps in this category, Zensify (iTunes link) doesn't just tap into one social networking service. The app is an aggregator, taking multiple sites and rolling them up into one app that will, in theory, make your social networking somehow easier. That's the promise of all these aggregator apps. So how does Zensify do?

First, Zensify supports Twitter, Facebook, Flickr, Digg, Delicious, YouTube, 12seconds and Photobucket. Unfortunately, I had only moderate success with signing in to some of these. Flickr takes you to the requisite Flickr-based verification pages, but after going through the process I received a warning dialog that an error had occurred, with only OK as my option to continue -- right before the app froze up completely. Then I tried Digg, but there was only a username field, not a password field. I was able to get Delicious to work, and YouTube (after quitting the app, as there was a bug preventing me from typing in the text area). I didn't try Photobucket or 12seconds, as I'm not big on those.

I should note that I wound up deleting Zensify, then re-installing it, and something interesting happened -- once I had re-logged into Facebook Connect, my previous logins "stuck." I only needed to type in my username on digg and it said everything was logged in. That was a pretty neat trick, and a re-install appears to take care of some of the initial bugs. I'm assured by the folks at Zensify that several other bugs are being crushed for the next release.

While Zensify is pretty in parts, there are functionality issues. These are because, in an effort to do everything, the app winds up a confusing mess at times. Many apps suffer from this, especially social networking apps. Keep reading for my full review.

The following app is rated for mature audiences. Reader discretion is advised.

I just had to write that, because, in the spirit of liability, Drinkspiration by Absolut (iTunes link) made me confirm my birth date upon initial launch. That, and I'd have a major guilt trip if little Jimmy went out on an all-night drinking bender because some iPhone app encouraged him to do so.

Like legions of apps before it, Drinkspiration aims to solve an age old question that has dogged mankind: What drink should I get? And while some like featured apps provide similar functionality, it's Drinkspiration's delivery that sets it apart from the crowd.

Back when we looked at Radar, a photosharing site with an accompanying iPhone app, I mentioned that while Twitter had monopolized the "text exporting" function from your iPhone, there would be a slew of companies to try and grab the rest of the media you want to broadcast. Radar, I said, wanted to be the photo app. And AudioBoo, it appears, wants to be the audio app (we've yet to see a strong video contender pop up with the 3GS, though YouTube is certainly serving for now).

I've been using AudioBoo (iTunes link) for a few weeks now, and I have to say, it definitely does what it says on the box: after a short signup session and the installation of the app to your iPhone, you can record and upload (and almost more interesting, listen back to others') audio quickly and easily.

You hit record, can talk for a while (i haven't hit a limit yet, though three minutes is what I originally heard, and that tends to be about right for these little mini-podcasts), then hit stop and upload, add a picture, title, and tags, and a few minutes later, your audio is right there on the web for everyone to hear. I've used it on my EDGE phone and my friend's 3G, and I have to say the experience is better on the 3G -- the upload speeds are much better (I generally have to wait on my iPhone until I get on Wi-Fi to upload the audio), and to my ears, the audio sounds better. Here's a recording I made at a Cubs game on my 1G with a few friends, and a recording my friend made on his 3G at a restaurant. Edge works, obviously, but the 3G seems to work better.

Danielle Cassley and Jason Citron are the folks with their names on Aurora Feint, but as Danielle told us in an interview a while ago, Peter Relan is the real mastermind behind the growing Feint empire. Not only did he put the two together in an idea lab, but he's one of the driving forces behind the OpenFeint enterprise. Under his oversight, the Feint folks have swelled to become one of the major forces behind iPhone gaming (and thus, behind the iPhone's app ecosystem itself).

Netanel "Net" Jacobsson is a newer addition -- he's previously worked with Sony Ericsson on their mobile devices and Facebook on their own growing app empire, and now he's arrived at OpenFeint to help them use the lessons he's learned at the biggest online social networks around on their social software. Get the sense of how big this is yet? Relan, Jacobsen, and Citron all have pretty big ideas about where iPhone gaming is going, and as 3.0 comes down the pike and introduces a whole set of new features from Apple, they're in the best seat they can be in to do exactly what they want to do.

TUAW sat down with the three last week, and chatted about iPhone 3.0 and why it's such a big deal for developers, how they're going to approach microtransactions (carefully), and what's coming next for OpenFeint now that they've rounded up a whole stable full of developers implementing their backbone.

In the ecosystem of the App Store, the postcard-sending app occupies a healthy niche; about two pagefuls -- 60 apps -- show up in the store, for a category weighting of 0.125 flatulans. The flatulan, of course, is the unit of measurement of App Store penetration, equaling the 480 individual apps that include the word 'fart' somewhere in their description.

Among those postcard apps, there are several standouts for virtual cards (ADA winner Postage, for example) and even a few that let you send physical postcards for a small fee (TapTapCards, goPostal and Postino).

With Postman (iTunes link/website), released today by Freeverse and Taptivate for $0.99 for iPhone OS 3.0 devices, the postcard-sending app category gets a social media boost. Postman lets you deliver your two-sided ecards (yes, the app gives you the option of simulating the back of a traditional postcard, complete with stamp graphic) via Twitter, Facebook, Tumblr, email, or simple upload to the postmanapp.com website for public review. You can already track several tweeted postcards (some which probably should never have been sent.) You can also simply save your postcards to the photo roll on the device.

Creating postcards with Postman is fast and easy; all the controls are persistent in a small icon bar at the top of the screen and large front/back and 'share' buttons at the bottom.

Postman has style and several handy features. In addition to using your own camera images/photo library or the included stock images for postcard sources, you can locate yourself on a Google map and use that graphic instead (this leverages the Map API in iPhone 3.0). Once you pick a graphic, you've got a choice of one-click filters to apply that spice up the look of your card. You can easily switch fonts and colors for your text input on the card front or back, and then send with a couple of taps.

There are a few rough edges with the first release. I found the lack of a portrait mode frustrating, as I'm actually a faster typist on the vertical keyboard; not that you'll be keying in a chapter of War and Peace, but there's quite a bit of room for copy on the postcard back and I'd like to be able to rotate on that screen. The selection widgets seem cramped a bit, particularly the one for the stock templates. It would be nice to save postcards in progress and switch back to them, but for now there's only one card and no way to revert to earlier versions.

If you want to have super-slick, email-only postcards from your iPhone, and are willing to spend a couple of dollars more for some added flexibility, you may be better off with Postage or the still-awesome Comic Touch. For $0.99, however, the first pass of Postman delivers ease of use and some very handy delivery mechanisms on the back end.
