I'm trying to explore all viable options for getting the new iPhone at a reasonable price. My situation, and this may apply to others, is that my wife has refused to upgrade the original iPhone I forced upon her (bless her) to an iPhone 3G. I, however, was not so wise. I would like to use her ATT account to purchase a new iPhone 3GS and then swap the SIM card with my iPhone 3G. Taking advantage of her generosity and patience, would you think that if I used her account to purchase an iPhone 3GS using her first gen iPhone, which she doesn't want, and swapped it with the SIM card of my current iPhone 3G that the accounts would be switched? My thought is ATT wouldn't care since they are still selling the iPhone 3GS to a qualified customer- My wife. My wife will get an iPhone 3G (my old one) and I would get my geek thrill by acquiring her new iPhone 3GS. Everyone wins! Any thoughts, or denouncements of my husbandly failings, would be appreciated. Thanks.
