hey guys question here.
i was thinking about preordering the 4S online. Im on a family plan on ATT and we have one upgrade available. thing is my family mixed up all the upgrades so the upgrade is for another line and not mine. I know they can solve this problem at the store, but i want to avoid the lines. So if i use the other line's upgrade can i just put the sim card from my 3gs into the new one? what would i do with the sim card they send with the phone?
any help or advice is appreciated
