The Sony Xperia T just came out, but you know Sony is already hard at work on their next flagship (and probably the one after that). A leaked user agent profile has revealed a phone codenamed Odin with a few model numbers; C6502, C6503, and C6506. That last number being the only different number could point towards regional variations. Unfortunately we don’t know too much more other than it’s running Android 4.1.1 Jelly Bean.
There are also two more devices that were revealed, but not as high profile. They are similar to the Xperia tipo and Xperia miro and their model numbers are C1505 and C1604/C1605. They both sport HVGA (480 x 360) displays and Android 4.0.4 Ice Cream Sandwich. The C1604/C1605 sports a Snapdragon S4, while the CPU for the C1505 is probably the same, but it’s officially not known.
