I finally switched away from my AT&T grandfathered unlimited plan to the new Verizon unlimited plan. Including the FAN discount and recent price increase, my AT&T plan rose to $89 which was still good -- before all this sudden unlimited data competition.
Now I've unlimited on my phone, 10GB of tethering which has already been useful and calling to and within Mexico and Canada. My unlimited Verizon plan will be about $92 including taxes and fees *but* I found out I have an employer discount with them which will take a few billing cycles to apply--so it may end up *cheaper*.
The data speeds on Verizon seem to be considerably faster than AT&T in my area right now and my phone works at my Mom's house. I never got service there under AT&T. Total win.
I'm so glad the FCC didn't let AT&T eat up T-mobile. However, I have a feeling the new FCC will not be nearly so consumer oriented.
