Psiphon – Open Source VPN App For Android

Psiphon is an open source, unlimited VPN app for Android that works great out of the box. It allows you to tunnel via half a dozen countries (or, automatically choose the fastest and most reliable option), and even compresses the websites you visit, thus saving you some precious mobile bandwidth.

Psiphon also has a VPN client for Windows that works much in the same way as the Android app.
