If anyone can help me I would appreciate it! I am trying to upgrade my iPad 2 that is on 4.3.3 to 5.0.1. However, I keep getting error message 21 when I try to update or get error 1600 when I put iPad in DFU mode and try to restore from there. It is currently jailbroken, but I want to update it to 5.0.1 until the jail brake for that firmware comes out. Anyone? thnks...
