So I have a dev. account with Apple. Couldn't get iOS 5 beta 1 to work, tried everything and it gave me some error. Now jump ahead (I skipped beta's 2-4) and I try and install beta 5, well I get the error code 20 in iTunes (yes it's the latest beta) thing is, I've tried this on all 3 computers in my house and keep getting the same error (20.) I don't understand what the hel* is going on! Yes, I am on a Windows 7 x64 machine and so are the other computers but come on, 3 different computers and the same error....seems awfully weird. If anyone has any help or suggestions I'd appreciate them, and yes I've read the Apple support page regarding error 20 and it did me no good. Thanks in advance.
