Hey, I talk from experience. Aparently running a VPN, exchange, and a soft phone is enough for verizon to suspend your wireless card. I was on travel to phoenix and the hotels free internet was down so I used my wireless card and after I transfered around 5 gig in a week they cut me off. it took my client over 2 months to reinstate the card.

One word "Sprint". They are sh*t for customer service, but they are pretty OK w/ you using their evdo bandwidth up. In fact, they don't even really enforce the fact that most trio users use their phones as a usb or wireless (bluetooth) modem....which is something verizon strongly relegates (to the extent of disabliing the feature on their phones).
