Sony Confirms ETA

Sony Mobile finally confirmed the target rollout dates of the official Android 4.3 Jelly Bean for Xperia SP, T, TX and V. It reported ETA will be out by the end of the month to early February after users got suspicious of the recent firmware posting removed at the PTCRB Web site.

"We hear you re: JB 4.3 for Xperia T, TX, V, SP - we're making final preps & will start rolling from end of January/early Feb," an official tweet from @SonyMobileNews.

Android 4.3 update was supposedly released in December 2013 but with some polishing to be done, delays occured unexpectedly. Leaked version of the expected release builds are available for manual flashing. However, owners who flashed the leaked version may still need to update via FOTA or Sony PC suite to get the latest features of newly approved builds by PTCRB.
