I had AT&T for about 15 months, then moved to Straight Talk, but now that I have the iPhone 5 I feel like a phone this good deserves LTE. Straight Talk can't even handle their 3G properly. Question - When I opened my account last year in April, I had to pay a $500 deposit, then got it back in April 2012. When I move back to AT&T after Straight Talk, will I have to pay another deposit? EDIT: Forgot to mention that I initially didn't have a contract, but a month-to-month. I'll be going back to month-to-month again sine I have an unlocked iPhone.
