I went from a 6+ to a 6, and am now considering going back to a 6+ after having spent some time with both phones. Someone contacted me on Craigslist who wants to do a trade and is willing to meet up at an Apple Store to inspect the devices and swap SIMs. Both of our phones are on ATT Next payment plans. When I spoke to an ATT rep today, he told me that we could just swap SIM cards and there would be no problem. Ignoring my obvious issues with indecision, I would like some advice on how to make sure this goes smoothly. The main thing I'm concerned about is the typical CL scam where somebody sells a phone and then reports that phone as lost / stolen several days afterward. Is this also a potential danger when doing a trade like this? Any other issues I should be aware of? Thanks!
