Are you running it currently? How is it if so?
It is still on my phone, and I have the app itself archived on the SD card as well. It works very well. You have to install an exe on your computer, and install the phone part on your phone, obviously. The exe on the computer even has an SMS agent. If you are using Pdanet and people are sending you texts, you can reply back on an instant messenger type interface on your computer. This keeps you from having to keep picking up your phone, etc.
My only complaint is sometimes you have to unplug and plug it back into the USB cable connected to your computer 2-3 times to get the app to sync when you initially start it. But once it syncs up with your laptop, it runs just fine. As long as your phone has signal, you have internet for your computer.
If you're interested, I would be happy to e-mail it to you. It really is a useful app, even if you only ever need it once.
