I’ve just found the single application for the Palm Treo that I just can’t live without! PDANet is a Palm application that turns a Treo smartphone (there’s a version for every model) into a wireless modem. It’ll even work via bluetooth on the 650 if you have bluetooth on your computer.

The application uses the digital data service on your wireless plan. On T-Mobile, it connects via GPRS. I already pay $19.95/month for unlimited Internet so I can get email on my phone. I thought that was expensive until now… Now I’m also able to connect to the Internet on my laptop from anywhere I have cell coverage.

I’ve been using it for several hours straight with no problems… it really works. I’d recommend this hardward/software combination for any mobile professional who needs a reliable way of connecting to the Internet out in the field.
