Rooting "might" void your warranty. I'm not responsible if anything happen to your phone (nothing should go wrong,, if something do go wrong, just repeat the whole process).

Update on Sony software upgrades, including uplift to Jelly Bean Android 4.1 for 2012 Xperia™ smartphones

December 17, 2012 - 4:02 PM

Hello everyone,

We’d like to bring you up-to-speed with the latest in our Android 4.1 rollout scheduling.

First up, the upgrade plans* for Xperia T, Xperia TX and Xperia V are progressing as planned – these smartphones will start to receive Jelly Bean during February and March.

Next up, Xperia P, Xperia J and Xperia go will be upgraded from the end of March. Then Xperia S, Xperia SL, Xperia ion and Xperia acro S will follow in the subsequent weeks.

We’re particularly excited about the Sony Xperia Jelly Bean features and functionality – we look forward to bringing you more information on this in the New Year.

The decision has been taken not to upgrade Xperia U, Xperia miro, Xperia tipo, and Xperia sola beyond Android 4.0.

Feel free to drop a comment below, and keep your eyes on the blog as we’ll be sharing more detailed news/updates as soon as we can.

*Availability and rollout timing will vary by market and customer variants

hello wooly i downloaded and installled xperia u frimware but i got a question it says in device info that my phone is ST25A tho its ST25i so i did something wrong or its supposed to be like this?

[Thommo]

A is for America, I is for International. The difference is in the Baseband support,

Nothing to worry about

[mhmed009]

thank you will i still get updates for my SI number from PCC or no?

[Thommo]

No - The SI number is only good for visual reference as to where or what part of the world your phone was produced for sale in,

The customization number is what tells Sony what firmware updates to give you - So if your changing to a different countries firmware then from now on you will get there updates via PCC or SUS
