I've had it for over 2 years. It's a 3GS. Today around 6 o'clock it just all of a sudden said "No Service". So I turned it off and then back on. Now it wont do anything but come up "Activation required" and then a black screen with the Apple logo. I even plugged it in to iTunes and it doesn't do anything. It wants me to Restore but I don't want to loose all my stuff. Any suggestions? Thanks!
