Telekinesis
I found another Mac app that lets you connect your iPhone and computer. This one works much better, and is much more powerful. Telekinesis allows you to have access to all your files, directly. You can easily view some, like text files or PDFs. You can also control your iTunes player a bit. It lets you grab both a screen shot and a iSight picture, live. Then, to top it off, it has a simple Terminal program that can let you do, well almost anything if you know how.
The only disadvantage is that you need to know the IP address and have access through your router. Easily done if you are on a static IP and control everything. Harder if you are on a laptop and using DSL.
