If true, you need to give a bit more details. I have talked to various reps about this, and they all told me that it's not possible. When you transfer the responsiblity to someone else, you drop everything, rate plans and features and the new person needs to sign up with a new rate plan and features. That's what I was told and I also remember it reading on a guide somewhere and even on one of AT&T's tutorials.
But if you managed to pull it off, post some details!
Are you guys going to a corporate store or speaking to people over the phone?
