My family's account with AT&T has 4 lines, and only 1 is eligible for upgrade. The phone number of that line in not my number. If I go to apple.com and pre-order an iphone 4, will I be able to enter the eligible line's number when it asks for the Phone Number, Zip Code, and Last 4 Digits of SSN, but use it on my phone number? Or can it only be used on the number used to order it at the lower price ($199 in my case)? A couple more questiosn that some of you might be able to help with who have gotten iphones in the past: 1) If I wait in line at AT&T on June 24 but don't get a phone, how long do you think it will be until I can get one that they order? 2) I know that if you wait at an apple store, all the reserved phones go first then if you don't have a reservations it's first come first serve. But is this the same for the AT&T stores? That is, if I wait in line early on June 24th at my local AT&T, will there be people who can just show up, walk in, and grab their phone whenever that day, or is it purely first come, first serve?
