I recently went back OTR and bought a AT&T 3G wireless card off of Ebay for about 1/4 of what the store wanted to charge.
Next issue, AT&T tried to say that even though I had my own equipment, I had to sign a two year contract. The only way I knew better is that the person I bought the card from used to own his own store and knew that was only a tactic. It took me about 5 or 6 separate times of calling in before we started getting somewhere. At first they changed their tune to, "you have to have at least a one year contract.", to finally I found one girl that signed me up month to month. I completed the sign up process immediately. It's bad enough that it costs 59.99/mo, but to be stuck with 1 or 2 years at that price even if you don't need anymore (or you have to pay that ridiculous early term fee.)
In a month and a half of using it, I've only not had signal once and that was last week at the walmart parking lot in Jennings, LA. As Bullwinkle said, Even though it's not always "high speed", it's something. I've found 3G to be quite fast, but usually only avail. in
large cities.
If I can get there early enough to find parking, and I'm not short changing myself on miles, I'll try and stay in the City only if I have plenty of time to take my full break. Most sites work great, but sites like google.com/maps take forever.
enough rambling...
