Best way to tether your iPhone – PDAnet

Unlike most apps that will provide a proxy web service to your computer through your iPhone PDAnet will provide a complete network solution for tethering your computer.  Basically, you can use your iPhone as a computer wifi device, without restriction.  While proxy apps will work well for web applications, it doesn’t work for stuff like email, ftp, ssh, etc. PDAnet can handle all network traffic.  I’m using my iPhone right now to access the internet from my Macbook Pro and it’s quite fast!  Check PDAnet out!
