I would like to get the iPhone 4 at launch and hand down my 3GS to my wife. She has Virgin Mobile and would like to port her number. (I know this is possible because I ported from VM when I got my iPhone.) I would like to add her to my account, converting it from individual to Family Talk. Can I do this by pre-ordering online? We will pick up the phone at the Apple Store (preferably) or an AT&T store (only if we need to, for some reason). I know all about backing up my 3GS' data on my PC ahead of time so I don't lose anything. I'm just confused about how AT&T handles their accounts and I'd like to get it all wrapped up within a week of launch.
