How did your IOS 5 install go?
1] Couldn't update my 4th gen touch -- a 4000 series error. Ended up having to restore then reload backups. PITA.
2] My son's 1st gen iPad kept getting stuck in recovery mode with an error # 4. Ended up downloading some haxor tools and attempted to downgrade back to 4.x (this failed too).
Finally had to use another tool, spoof an apple authentication server, and finally got IOS 5 forced into it. Was up until 2AM.
Not a happy camper.
TLDR; Not a smooth install on two devices.
