Problems after unlocking my iPhone with ATT
After unlocking my iPhone 3GS with ATT and going through the restore process via SIM card, WiFi and iTunes, I am unable to re-activate my phone.
Using a T Mobile SIM card and/or via WiFi I get a message that the server is temporarily unavailable. When I try iTunes, I get a message indicating that there is no SIM card inserted when it has one in.
Help?
