Can I downgrade?
Hi I got an ATV 2 and I upgraded stright away to the latest software to be able to try airplay.
Can I downgrade so I am able to Jailbreak?????
Did you get a SHSH for iOS 4.1? Apple might still be signing 4.1 SHSH requests.

Without a 4.1 SHSH for your device, you can never restore to stock iOS 4.1 again.
Please read the stickies & search forum before posting! How to report an iTunes restore/update fail in a useful manner
iPad 3G 64GB (4.3.3, Redsn0w) oldest SHSH 3.2.2

iPhone 3GS 32GB (4.3.3; Pwnagetool) factory unlocked oldest SHSH 3.1
