Hello, Id like to get an iphone 5, but Im not eligible for an upgrade until the Fall of 2013. I wanted to end my AT&T contract and sign-up with another carrier. A couple of years ago, I saw video which indicated the steps to end your contract if your monthly rate increased (even by a few pennies). I was going to give that a shot, but I wanted to know has anyone tried this? Any other recommended approaches? THANKS!
