My wife's line isn't eligible for an early upgrade. AT&T wants 599 for an iPhone 4. Has anyone thought about. Doing this if you're in my shoes? Add a new family line and get an iPhone 4 for 199 and port out your old line and get an early termination fee of around $100 since she has had the phone for a year. Therefore the cost of a new phone is $299. AT&T said that I would have to wait 60 days to port the line back in otherwise it would be considered a win back. Just trying to think of if it's worth it.
