We have 4 numbers we want to bring over from T-Mobile. I've been playing around on the Premier site in preparation, and it only asks me if the primary line will be using an existing number (on the very first screen). I haven't seen anywhere to indicate that the other 3 numbers are coming over as well (it only asks what area code I want). Does this mean I won't be able to pre-order our 4 iphones online next week? ATT store is across the street from my office so it's no big deal, but I'd rather just point and click my way and have them delivered to my doorstep.
