I'll stick with my WiMax 4G Clear Stick. $42 unlimited Data that I can get from 6mbs to sometimes 10mbs monthly no contract. (Though it's now $50+ per month now. I got mine back when Clear launched, so I'm grandfathered in on lower price)
I forgot to mention, its ONLY on their 3G network, which every where I have ever tried it is slower than Verizons 1X and AT&T's EDGE..(LA, San Francisco, Central Valley, Sacramento, San Diego, Atlanta, Miami, Las Vegas just to name a few)
