Those of you who happen to own the Asus Transformer Pad Infinity TF700T and are looking forward to the Android 4.2.1 Jelly Bean update on an official basis, here is news for you: continue waiting. Sorry to say, but that is the way things are moving at the moment, but for folks who are willing to take the plunge with an unofficial ROM being released by the good people over at XDA Developers, then why not give it a go?
Just to get an idea on the kind of dedication that is behind the Android 4.2.1 Jelly Bean ROM, how about this – the audio code alone has been specially written from scratch, enabling the audio to play nice with the update. You will not find full functionality with this though, as both GPS and camera functions do not play nice, and as always, running an unofficial ROM carries with it its fair share of risks, so proceed with caution! You know, buyer beware and all that jazz.
