Late again :)
Here's my cool site of the week for BlackBerry users - Tetherberry! http://www.tetherberry.com/.
A sweet BlackBerry app that let's your phone become a usb modem. Introductory pricing is $29.99 for the PC software (currently works on PC only) and the device app.
I purchased this software over the weekend and was able to tether my phone to my laptop and surf the web at really good speeds on my phone's Sprint Rev A network. From what I hear, the app uses your phone's data connection so you don't need to purchase any phone-as-modem service from your carrier. I had a similar app for my Windows Mobile phone (PDAnet).
Excellent app, works great at a very fair price.
