Sorry guys, I started this thread after I switched. Unfortunately I was quickly disappointed with the network. One too many "no network found" in areas of my town. Also Verizon called me on a winback, and agreed to waive my ETF and join their edge program despite being only 7 months into a new contract.
So I'm back with Verizon. Also Verizonnow has several new single line plans with lower costs. Including a $45 plan. So T-mobile has certainly shaken the industry, and we should all thank them for that. Now if they could only improve their coverage.
