Sony Updates Its Jelly Bean Timeline For 2012 Xperia Devices

Sony released more details on their official blog for Xperia owners patiently awaiting for the upgrade to Android 4.1 Jelly Bean. The company confirmed that the Android 4.1 update is still on schedule for the Xperia T, TX and V, which should roll out in the beginning of February and March. Xperia P, J and Go owners will have to wait until the end of March for their update, while Xperia S, SL, Ion and Acro S users will receive their update in April.

Sadly it appears as though Xperia U, Xperia miro, Xperia tipo, and Xperia sola users will not be sharing in the upgrade euphoria, as these devices will not be updated past Android 4.0
