This perhaps goes under "should have asked first...", but can someone tell me how an existing AT&T mobile account (wife's) that was added to my account (and then made part of a new Mobile Share plan) is affected beyond billing? The "new" number showed up under my name when I look at my account online, and I've changed the user profile information for that line to her information. I was told by the AT&T rep that I could change the Caller ID name to hers, but haven't figured out how yet if it's different than changing the profile information. My big question is whether that affects her use of the phone with iTunes. Any experiences/thoughts would be greatly appreciated! Thanks in advance.
