The Xperia GX passed muster at the FCC labs a few weeks back and is filling shelves of NTT DoCoMo stores starting today. If you like your smartphone screens big and high-resolution, you'll probably be very happy with the Xperia GX's 720p 4.6-inch display, wrapped in a curved frame similar to last year's Xperia Arc. There's no word on whether the phone will remain a Japan-only exclusive, but Sony is likely to have something new to show off at European trade show, IFA, in only a few weeks. Arguably more of a looker than the Xperia S, perhaps we'll see a global model -- there's a pentaband 3G radio in this iteration -- sidling up next to an Xperia tablet in Germany very soon.
