I need to replace my phone asap but am still under contract with AT&T until September and not eligible for an upgrade without paying through the roof until then. My wife's phone was financed through AT&T Next, and just paid off completely a month ago. She's happy to keep using it and hold off on upgrading, so I'd like to use her account to get me a new phone. From what I've read, I can buy a new phone under her name and activate it on my line, but I'm fuzzy on the details. Ideally, she would then upgrade her current phone using the upgrade options that will become available on my AT&T account later this year. So is this possible and can it be done through the apple store or do we need to go into an AT&T store to handle our out of the ordinary activation needs?
