I have an iphone 3gs that I just upgraded to OS 5.0, however, I don't use it as my cell phone anymore, I just use it as an itouch because I upgraded and switched carriers. When I updated it to the new operating system it reset it and is making me activate it, however, it cannot be activated since the sim card is not inserted, and if I was to insert it then it would be an inactive sim card. How do I either bypass this or do a backup on it? Or would it be easier to jailbreak it since iTunes is a massive pain?
