The mods can whack this one if I'm not supposed to link to another forum, but a few of us have been doing our best to compile some real data regarding download speeds and such from the various wireless carriers. You can see the map I've been updating at this link:

It seems that Sprint (which I use) is the most common provider, and I have been happy with the service more often than not. Around the end of last year, a whole lot of places went from slow to fast as they did a big upgrade. It isn't exactly a thorough and scientific approach, but every little bit of info is useful. In some places (El Paso, e.g.), AT&T is fast and Sprint is slow. In others (my hometown, e.g.) Sprint is fast and AT&T is slow.
Anyone can feel free to log in and add data to that thread, BTW. The more info, the better. I update the map whenever I'm not feeling too lazy.
