Why not just use a cheap GPS receiver instead of a WWVB receiver. It should work anywhere in the world, and give time keeping accuracy better than 1 microsecond relative to UTC. Most of the time location accuracy is around 10-30 meters, so equivalently the time error at a GPS receiver is 35 to 105 nanoseconds or so relative to GPS time that is maintained to within 100 nanoseconds of UTC. If you want to see the past week's relative error, try http://tycho.usno.navy.mil/gpstt.html.
The Sprint PCS and Verizon networks, and probably others, are synchronized to GPS as well, but I have no source for the time keeping accuracy produced by your connected wireless phone.
