I live in the middle of BFE and have to use an old iphone with 3G unlimited as my internet (we have no cable, no Verizon fios, no ATT ... and heck if I am paying for DSL at the speed of smell, or Sat internet). Anyhow, once P188 arrives, I am taking that out of the house and putting it in the car (tethered) and will change the house over to a T-Mobile hotspot at 4G that has a good signal profile for my location. I am not too worried about the connectivity speed, as I don't really care too much about the maps, but Pandora and TuneIn are quite important to me. WGR550 was too, until the blasted NHL lockout.
Anyway, that is my plan, and I am sticking to it.
