I bought an iPhone 3GS, second hand, and I have now found out its on a AT&T network. I live in the UK, I can't get past the "Connect to iTunes" message. Even when I connect to iTunes it says:
Phone not found. Please try again later.
I can't get into the settings on the phone either. Do I need to unlock the phone from AT&T? If so, how can I do that? If not, how can I get past the errors?
