Like many, I got my 4s on release date. It says it would cost $849(or was it 829) to get the 64gb version and no upgrade price till 2013. But apple's app said if I wait till the 8th I could get the phone for $649? But I'm sure I I wait, I'll be way more than the extra 3 weeks b4 I I would get the phone. Any ideas what I could do? Like if I have two phones on my account, my other# can be upgraded. Could I get it and then switch Simms once I get the phone at the AT&T store? Yes I know it'll be different size sims.
