I live in Davenport, part of the Quad Cities, and we were supposed to have gotten 4G in the past few days. I'm in the heart of the area and still only get 3G. There are only a few places that I am able to connect to 4G and that is only for a very short period of time while I am driving. I can't connect to it at home, work or pretty much anywhere else I go. Is it just going to take like a little time for the whole area to be covered or something? 4G is one of the reasons I bought a Thunderbolt and am just kinda clueless right now...
