absolutely. only thing keeping me with vzw for now is strong LTE in this area,and grandfathered unlimited data. all my contracts are up. i can save a considerable amount F $$ by taking my 4 lines to t mobile,and when i do so,i intend to inform whomever i have cancel service the main reasons are:
1)slow updates to the intergation of all vzws bloat
2)their efforts to keep high end htc's off the unlock list
as you said,if enuff folks do it,they may change.
