Yesterday we heard that ASUS was rolling out the Jelly Bean update for the Transformer Prime in Sweden, and today we have confirmation from ASUS' Gary Key that users in the U.S. and Canada will be seeing Android 4.1 for their Prime and the Transformer Infinity in the next 72 hours.
The version number will be 10.4.4.14.1, which is Android 4.1. We have no further details other than what ASUS has already mentioned, namely that the update no longer officially supports Adobe Flash, and that on the Prime Wifi direct has been removed.
Key has been a reliable liaison between ASUS and the Android community, and as an ASUS employee he doesn't have to rely on second-hand information. Get your tablets ready, because it certainly looks to be coming soon.
