Sony offers Jelly Bean ROM for advanced developers with an unlocked Sony Xperia T
limited functionality. For example, you will not be able to make phone calls with it installed on your phone. Sony says that this update is for advanced developers only and if you do not know what you are doing, you are on the way to bricking your phone if you flash the ROM to your device. You must have an unlocked Sony Xperia T and must use Sony's Unlock boot loader service and agree to all conditions. As usual, you will most likely lose any warranty on the phone once it is unlocked.
The following statement is important. If you unlock your phone, you will not be able to receive the final version of Jelly Bean when it is ready to be disseminated by Sony. Some of the features that will be turned off if you flash the ROM on your Sony Xperia T is Gmail and Google Maps, any phone service, Bluetooth, Wi-Fi, NFC and the FM radio. The UI will not reflect the final Jelly Bean look and feel that the update will have when it is officially released. So what is on the ROM? Sony says it includes a number of Jelly Bean features that it knows developers will enjoy.
If you're interested in giving Sony some input on Android 4.1, you can use Sony's flash tool for unlocked Xperia models. All the directions can be found at the sourcelink. We'd suggest that if you aren't an advanced developer, your best bet is to stay on the sidelines and leave this to the experts.

so whats the point of testing....? wakelocks are usually kernal related, dealing with bluetooth and modems.... no signal no problem... nice try sony but at least give a functioning rom to test before you declare the warrenty is void

Sony disabled such functions so that others won't be able to sell a phone with unstable jellybean i think lol... not sure though, just my guess

Maybe sony just wanted feedback on the functionality that they provided.

Oh! Are they still planning to update their current phones??? Its taken so long i began to think they had also given up hope, even the 2yearld GS2 is already receiving 4.1.2, happy waiting to the Sony users, especially them poor Xperia S users, gotta feel bad for them, lots of promise, hardly any delivery, its a damn shame.

The ics of gs2 announced at March 2012, but my sister just updated at November 2012, now the jellybean announced for Spain only, and you have to wait at earliest June, if you unlucky enough

Whats the fun if nothing required would work. Some stunt to gain visibility in media because GS2 is getting JB update and Sony's ICS update and a fix firmware after that has hosed many devices camera functioning (Xperia P for instance)?
