Sony mobile have confirmed the roll out of JellyBean has started for the Xperia S.
Although I should imagine it'll be a while before O2 customers see it, the ball is rolling!
Personally can't wait for the ftf to appear on certain websites so i can try it!
A plea to MI5 etc, those websites you use to see what firmware has been released on what networks/regions etc.... you don't happen to know the Sony one do you??
Track usage, upgrade and get support with the My O2 app
