My very nice girlfriend let me use her upgrade to buy an iPhone 4 from apple.com (she gets my 3GS to replace her old 3G). It is supposed to arrive in the mail as early as tomorrow. Has anyone on here successfully bought a phone on one line and then used it on another line (not on a family plan) without going into an AT&T store? I have seen claims that it can be done over the phone. If so can you give me some idea what information we would need to make this work over the phone? I've seen mention of: sim numbers (is that printed on the card?) IMEI (can I get that without activating the phone?) SSNs ...but none of the threads I found while searching were by people who had actually done the swap (just people planning to do it). She will be at her work, I'll be at my job in a different location, I don't think we will be able to meet in the same location (let alone an ATT store) until Tuesday night and I would absolutely LOVE to not have to wait to use my shiny new iphone.
