Just a quick question for the experts. Verizon seems to work much better in my area for calls and data than AT&T. I've already tested it and tried it out, just now need to make the switch. However I am with AT&T and bought the new iPhone 4S roughly 2.5 weeks ago. Before I bought the phone and was not in a contract at the time. I also paid the full price for the phone, which was the $449 for the 16gb phone. Is their a penalty for me leaving now that I bought a new phone? Even at the full price? I fear that when I bought the 4S, I signed an agreement that locked me in for another two years. If so, don't I have 30 days to return the phone and cancel my service?
