An app that is a SOCKS Proxy. It allows you to connect your laptop to the Internet through the iPhone's 3G/Edge connection (tethering) without having to jailbreak your iPhone. If you want to install the application on your iPhone you will have to build and install the App from the the supplied code. The code does not use any undocumented APIs. Apple will NOT approve such an App on its store so you will have to build it yourself.
