Hi, I was recently given an iPhone 5 to sell for a friend but he has AT&T and I have Verizon. My problem is, I can't get past the iOS 6 activation because I don't have an AT&T sim to put in it. I tried my verizon sim but it doesn't work, is there any way to get around this SIM card thing? I just want to be able to go to settings and see what version of iOS it's running. Any help is appreciated, thanks!
