There appears to be some chatter on Asian tech sites that the Android 4.1 Jelly Bean update for the Sony Xperia T and Xperia TL (for AT&T) is being pushed out. We have come across two screenshots showing the About screen of the Xperia T using the 3.4 kernel and Android 4.1.2. One site shows the international version of the Xperia T (LT30p) with firmware version 9.1.A.0.420, whilst another shows the AT&T version of the handset, the Xperia TL (LT30at), with build number 9.1.F.1.64.
Before everyone gets too excited, these updates are highly unlikely to be ready for public consumption. What we’re looking at is either fake (however given the two separate screenshots, we assume that they are real) or a development version of the software that has leaked. Sony Mobile has talked about a February 2013 release date for Jelly Bean for the Xperia T and if it planned to release it earlier it would have said so.
Xperia T (LT30p): Build number 9.1.A.0.420 (Android 4.1.2 Jelly Bean)
Xperia T (LT30at): Build number 9.1.F.1.64 (Android 4.1.2 Jelly Bean)
