I recently restored my sons phone to factory, unable to activate it on iTunes and/or through the phone, keeps receiving "could not be activated because the activation server is temporarily unavailable or there is no SIM in iphone". Any ideas on a work around?
1. Your antivirus or firewall on your computer is blocking the connection to gs.apple.com
2. You used your computer at some time in the past to jailbreak or hack an iDevice. This corrupted your network database, and you will have to edit your hosts file and remove any lines that contain gs.apple.com.
