Apple has released Apple TV 5.1, and it has a very nice feature I would like to have – fast user switching. But is it safe to upgrade, or will that break aTV Flash? (I have a 2nd gen Apple TV running 5.0.2 and aTV Flash 2.0.) I couldn’t find any mention of the 5.1 release here. Thanks.
At the moment there is no jailbreak for the 5.1 software so if you parade to it you will lose your ATV Flash.
