I have two lines that are only eligible for the early upgrade pricing. My plan was to activate 2 new lines and buy the iPhone 5's at the two-year price. I was then going to transfer the iPhones to my current lines and put 2 dumb phones on the new lines, keeping them at $9.99 a month. That way I'll have an upgrade every year. An AT&T rep told me that their new policy is that of you activate a smartphone on a new line, you're required to keep the data plan on that line for 6 months, which would make it no longer worth it for me. This is the first I've heard of that, and I'm not sure if I believe her. Has anyone else heard that?
