When I first got the iPhone 4S I didn't have a SIM card ready to go into it, but I found a way to bypass the SIM card activation and I could use the home screen as normal, except when I pressed the lock screen it would go back into activation mode again. So when I was in the home screen I downloaded an app, but then I guess I locked it and it went into activation mode again. The app is still on waiting now. I've tried resetting with the home and lock button, I've checked iTunes for any stuck apps, I reset the whole phone, I've tried to delete it through my computer but none of it's worked. Help! Thanks.
