UFC Undisputed 2010, a universal app for iPhone, iPod touch, and iPad, has just been updated with Game Center support and better still, it’s on sale this weekend — 70% off — in honor of the GSP fight… er, UFC 124.

The Game Center update includes leaderboards and 19 different achievements. And really, when you throw the high-knee knockout, slam someone senseless, ground-and-pound them into the next round, grab an armbar that’s sweet or lock on a triangle and put them to sleep, you want all your friends to know about it, right?

MMA fans and UFC junkies, check out the complete feature list and more screenshots after the break, and if you try out Undisputed 2010, let me know what you think.

And here’s to a great fight tonight between GSP and Koz tonight!

Every week a few of us from team TiPb, bloggers and forum crew alike, will bring you our current favorite, funnest, most useful App Store apps, WebApps, jailbreak apps, even the occasional accessory, web site, or desktop app if the mood strikes us. As long as they’re iPhone (or iPod touch) related, they’re fair game.

So who’s on deck this week and what are our picks? Find out after the break!

James’ Pick: Appigo Todo

As a heavy Outlook (and therefore Exchange) user, one shortcoming even the highly anticipated 3.0 upgrade does not address is the management and synchronization of tasks. Although I was initially disappointed, Todo by Appigo has filled the void quite nicely. Todo is a robust app that can organize multiple todo lists, projects, and even manage your shopping list. One great feature of Todo is the ability to sync with Toodledo, Remember the Milk and even has a free desktop sync client. For more information, see the uber review as put together by TiPB’s very own Matt Sawyers (msbaylor on the forums). [$9.99 - iTunes link]

Jeremy’s Pick: UFC Undisputed 2009.

[Ed: Not an iPhone app, but Xbox 360/PS3 and what's held Jeremy hostage lo this last week!] I’ve been waiting for this game for a very long time and my patience has paid off. Must have for any gamer who loves mixed martial arts. Anyone out there who thinks they can take me… You know how to contact me.

Leanna’s Pick: Word2Find

This is a quick little game that tests your vocabulary and unscrambling skills. You are given 6 letters and must produce as many words from them within the time limit. There is always at least one word that’ll use all 6 letters. Word2Find is one of those games you can get away with playing while in class or a meeting… not that I would ever do such a thing… [ $0.99 - iTunes link]

Matt’s Pick: Tweetero

Yes, Tweetero is a Twitter application and while is has all the usual standard Twitter actions, what put this on my radar was that it allows you to save Tweets that you can send later. Of course it doesn’t have all the nifty features of say, Birdhouse, but it is nice to have the option to save, edit and send later (or even send all saved). The interface is rather simple and the Home layout is reminiscent of Tweetie, best of all this little gem is free! [Free - iTunes link]

Rene’s Pick: iStat

iStat is by Bjango, whom you may know by the name iSlayer on the Mac, makers of the awesome iStat series of widgets of the same name as this app. Confusing? Maybe, but the app itself is as simple as it is awesome. It shows you all kinds of nifty stats and measures about your iPhone (and even lets you free up system precious system stats or email your UDID at the touch of button), but here’s the killer feature — it shows you stats for any Mac you’ve connected to as well. Want to know how hot your MacBook is running in the living room or what your Mac Pro is doing in the office without getting up? iStat makes it easy. If you have an iPhone and a Mac, and any sort of geek-cred, you need iStat. Best of all, it’s at sale price right now!
