Okay - here's the situation. I am getting a new phone through work (iPhone 4S!) and I want to dump my girlfriend's line and move her to mine. The reasoning is I don't want to lose my rollover minutes and I'm grandfathered in to unlimited data with my current AT&T plan. I want to move her to my line but she wants to keep her phone number. Does anyone know what I have to do with AT&T to accomplish this - or if I even can? She'll take my old number if she has to but she'd like to avoid it if we can. Anyone have any experience with this? Any thoughts or suggestions? Thanks in advance.
