Hello all... New to the forum and I have a quick question about upgrades. If I have missed posts that I need to be looking at first before posting my question, I apologize in advance... Please direct me to them. Otherwise... I have an AT&T account with two lines... One I just added in October. The first line isn't due for an upgrade until July of this year but the iPhone 4 is broken for this line... Being that Best Buy had a great deal on iPhones, I bought a 5C for free on a new, 2 year line. Can I take this new iPhone and put it on the broken phone line and then cancel this new number without having to pay Best Buy full price for the phone within the first 14 days? Will AT&T recognize this and perhaps charge me account directly for the full price of the phone? Please also note, the original line that is broken only have a $150 ETF... So all in all I'd be only paying the $150 for the 5C, but looking to avoid that fee obviously.
