I preordered my iPhone 5 from AT&T and it arrived on 9/21. I've been grandfathered into unlimited since the original iPhone 1, so I'm able to have "unlimited" LTE with throttling that starts at 5gb rather than 3gb for non-LTE plans. I'm now realizing that there is Verizon LTE around my suburban area, but no AT&T LTE. I'm willing to forego my "unlimited" since I use about 6-8GB a month anyway, and I end up being throttled for the last week or 2 of every month. Plus, I want to be able to tether to other devices as well, which AT&T "unlimited" plan won't let you do (no FaceTime either, but I don't care). Can I return my AT&T iPhone and switch to Verizon? Doesn't AT&T have a 2 week return policy?
