iPhone 3GS activation with iOS 5
Hi there,
So I'm helping someone out with updating iPhone 3GS to iOS 5. Here's the thing...the iPhone was unlocked so that it could be used on T-Mobile. But now the phone is not a phone anymore and acts like an iPod Touch and wanted to upgrade to iOS 5, so I restored it with the iOS 5 ipsw package. I obviously had to switch the T-Mobile SIM card out with my dad's old AT&T SIM card, and tried to activate the iPhone 3GS and it keeps failing all the time no matter what I do! I cannot get past this and am trying to figure out why it's not working. I'm going through the iOS 5 setup, and I don't want to activate it as phone and want to keep it working like an iPod Touch running iOS 5. Any suggestions anyone? I hope an answer can be found soon...by the end of the weekend preferably...
Thanks!

P.S. I have it plugged into iTunes (10.5, Windows 7), and it says that there is no SIM installed when obviously the AT&T SIM card is in there....
