Ok, here's the deal; I'm the primary holder of a 5 line family talk account. I already have an iphone 3gs, and I'd like to get one as a gift for my wife at Christmas. Problem is that our only upgrade we can take is from my mother's line. Mom is fine with giving up her upgrade (doesn't care what kind of phone she has). But she's 245 miles away. How do I get the upgrade before Christmas, keep both my mom and my wife's current SIMs/Phones working, and keep it as surprise for my wife? Please help!
