I just started using Verizon Wireless EV-DO with my TR3A. I’m amazed at the jump in speed from EDGE. I live in Boston, and I’m averaging a slow DSL speed at anything above 50% reception. I get roughly 50-60 KB/s download at full strength.
The reception has been excellent everywhere I go—the only downside to this is that it’s $80/month. But if you need access where you go and can afford it, it’s probably worth it.
