I am using KB1. Chickmag11, I am in Ardmore, OK area, which is a 3G city all over. But certain areas of the city service sucks. But also in certain places of the city, I can get a 3MB song to download in about 10 seconds (usually when I'm closer to I-35). As for OKC, I went to Norman a few weeks back, and service, texting, internet was all full bars, and super fast.
