I think your pretty much right on, ATT LTE is very good in Omaha its not hard at all to hit high 50's download. Most I people I know in Omaha are on VZW followed by Sprint then by US Cellular. I just know a couple on AT&T. Tmobile is a joke with coverage, altho they do have 42MB rolled out and if your close to a tower you can get LTE like speeds.
