True TMO needed to have asked for a much better roaming agreement with ATT even if only for talk and txt. Speeds of mobile data are great but coverage is king and trumps all. If you cant get the basics in all locations you no longer want the service there providing. The main reason people flock to Verizon and keep them at number 1 is coverage. This would have allowed TMO to focus more heavily on making sure there own current Tower footprint is upgraded to the fastest data network they can provide meaning as long as your on it your golden, all while still allowing there customers to have real nationwide coverage.
PS holes in NY city don't tell me that Im on my way there friday! last time I was there coverage was pretty good speeds however sucked. ( note I stayed most of my trip in Manhattan and parts of Long Island)
