Hello all, I have a (hopefully) quick iPhone/ATT question... First, if one wanted to 'test' the ATT network out in their area (for me, SoCal - Area Code 562 and 714) to see how the reception and call quality is, I can pick up a freebie and have 30 days to do so. However, if I am to make the switch, I'd like to get an iPhone. Therefore, since my iPhone is unsubsidized, I should be able to keep the freebie and if it all works out, get the iPhone too. Will this work? I'd prefer to have the freebie as a spare in case the iphone ever needs to go in for service. Thanks!
