This Sunday, your phone can help you gamble. It can also let you become a carjacker for one brief moment, and bring you closer to the lovely Ben Gibbard. To the Store.

Payback: It's no Chinatown Wars, but Payback is a solid GTA-clone for the iPhone. Lots of guns, lots of driving, and really, really solid graphically. I prefer my iPhone games more on the play-for-2-minutes puzzle side, but Payback has a neat auto-save feature that lets you pick up right where you left off once your sandwich is ready and it's time to stop playing.

Office Pool: This guy kind of priced himself out of the market, since, well, a paper and pencil works pretty well for this too, but if you want to create and track your illegal box pool on your iPhone, $5 will do that for you.

Death Cab For Cutie: Surprise iPhone-loving Trent Reznor didn't beat those emo weenies Death Cab For Cutie to the iPhone app game, but this is still pretty cool. The free app links you up to ten free streaming songs, news, tour dates, videos, and of course the chance to buy stuff. Pretty nice design. If you still heart Ben Gibbard's dulcet honeyvoice, this is for you. Free.

Fullbrowser: One of the more interesting new browsers now that developers can re-skin Safari is Fullscreen, which removes the title bar for normal browsing and overlays a nice translucent bar when you need it. And, it's free.
