Hi, I'm going to buy an iPhone tomorrow, but I want to confirm one last time now that people have more experience with it if I can get an iphone for the $199/$299 price. Line A - my line that's not eligible for upgrade Line B - other person's line who is eligible for upgrade I'm on a family plan, and as of right now, Line A is not eligible for an upgrade. However, Line B is. So what I was thinking is this: Go tomorrow and buy it for the normal price and get it activated on Line B. When I get home, swap the sim cards so that the numbers don't get mixed up. Call AT&T, and have them move the iPhone plan from Line B to Line A. I know that I could just get a MediaNet plan, but Line B is gonna have a data plan, so Line A might as well get the one with Visual Voicemail since I'm on the iPhone. Please tell me if this is possible.
