I just took my iPhone 4S out of the box and turned it on. I began to do the process of activating, and then I got to the "It may take up to 3 minutes to activate your iPhone" and every couple of seconds the message glitches. After waiting more that 3 minutes, the phone says it goes to the Could Not Activate iPhone screen, and that I should restart the phone. I've done this multiple times now and it's still not working. I don't even know what to do at this point. Please help!
