Hi all, Little sticky situation: I was on the midst of ordering iPhone 4s for myself and my mom. She is on my plan and I thought it would be a nice gift ;-). However, in two weeks time she had two phones crapped out on her. And with the whole 3 weeks waiting time for the iPhone i need some kind of stop-gap plan b/c the 2nd phone that broke was my old backup. I was thinking of using a at&t go phone and transplant the sim from the broken one. Has anyone tried that?
