GizmoCanada.com, its unofficial Asus Transformer Pad Infinity page, and their users have shined a bit of light on the latest Android OS from Google. See insert below.
A lot of rumors are swimming around about Jelly Bean OS for the TF700T, and I believe some people are jumping the gun, now I know the update will go OTA in the coming months, as ASUS stated about a month ago. TF300T owners are lucky enough to know that the update WILL push out very soon, if not already. One site claims that updates are rolling out for the TF700T already, but almost 2000 users over at the Asus Transformer Pad Infinity Facebook Page (unofficial) it hasn’t been seen.
So I guess all you TF700T owners will have to wait and see. If you are rooted, you will be out of luck, although modified ROMS will be released into the wild soon after the official OTA goes out. You must have patience, personally I think TF700T users waited long enough just to get their tablets!
