The other day we’ve seen an “official” Ice Cream Sandwich update leak for the AT&T Samsung Galaxy Note and today we’re bringing the AT&T Samsung Galaxy S II ICS leak to your attention.
As the description in the thread states, “this is the official “leak” of Samsung’s ICS UCPLC5 firmware”. It appears to be Android 4.0.3 with the other info as shown in the screenshot below. The latest available version is rooted, deodexed, and “other than Root and CWM Recovery this is bone stock”. If you understand the risks but want to give it a shot, follow the source link below for download, instructions and a lot of feedback.
