My boss just bought himself two iPad 2's. We've already got them set up to sync under one iTunes Store account and two computers(to keep them exactly the same). However, if he sets up the AT&T data account, can he use it for both of them? In other words, can you pay for one set of pre-paid data, but use it on both iPads? He wouldn't ever use them at the same time, so why pay for two plans?
