I'm considering switching to TMobile, as my bill would be half of what it is with AT&T. Plus, getting tired of AT&T restrictions/practice on things like restricting built in functionality (Facetime on iOS devices, video on Google Hangouts on Android devices, Charging extra for tethering, etc). Currently live in the northern burbs of Detroit. Does anyone on here have any experience with an AT&T 4S and/or 5 unlocked and now on Tmobile who lives roughly in this area? I have both phones (my wife's and mine), and was wondering what your experience has been like. Are you still glad you switched? Are you noticing any pitfalls, or especially bad coverage areas? Are you getting LTE on the iP5 yet? I spend 90%+ of my time in this area, as I don't travel for work, so only occasional vacations would be of issue, but since it's a vacation, it's not a huge deal if I lose coverage for a bit while travelling.
