Thinking of early terminating my ATT 4S and going with Verizon

[davester]

I'm trying to do a similar calc, but we have 4 iPhones on a family plan, 2 in and 2 out of contract. I'm sick and tired of lousy at&t coverage and despite promises it has not gotten any better over the years. The phones just plain don't work in too many places. It's very tricky to calculate how much it'll cost to switch.

BTW, where do you get those high resale prices for your existing phones? I haven't seen anything like that.
