(Worldcarfans) - Wow, sure enough, those green buttons are straight up legit -- who'd have thought? The long-rumored GSM cut of the Palm Centro is now officially available on AT&T in the wake of Sprint's expiring exclusivity, giving a whole new world of customers access to the freakishly small (yet strangely adorable) Garnet handset. Unlike Sprint's version, the GSM Centro tops out with EDGE data for a moderately less snappy browsing experience; otherwise, though, your $99 on contract is going to buy you a 1.3 megapixel camera, microSD slot, Bluetooth 1.2, support for AT&T's push-to-talk service, and a full (albeit miniaturized) QWERTY keypad. So who's liking this more than the white / gray scheme we'd seen before?
