Really tempted to switch, I like T-Mobile's pricing. I have a grandfathered unlimited data AT&T account on my iPhone 5 but I don't like AT&T restricting my ability to use FaceTime or Mobile HotSpot unless I switch to a tiered data plan. Only thing holding me back is figuring out how T-Mobile's coverage is in my area. Price wise T-Mobile monthly for $70 is cheaper then my current AT&T plan with a 24% Fan Discount.
