EDITORIAL REVIEWS

"Private Internet Access, one of Lifehacker readers' favorite VPN service providers, makes it easy to surf privately and securely from anywhere." -- Lifehacker

"There have been several Editors' Choice VPN services recently, as one product tops the next, but Private Internet Access out-performs and out-features the competition. With 4.5 stars, Private Internet Access sets the bar high and is truly the Editors' Choice, trumping all our previous favorites." -- PC Magazine

GENERAL NOTES
* Application is available for Android 4.0+ with Direct VPN Support
* Application is available for Android 2.0+ as a shortcut to the VPN Settings

You need a root device the tun/tap driver and busybox.

OpenVPN Installer will try to install openvpn (2.1.1) in /system/xbin or /system/bin. Your mileage might vary depending on your phone.

Androids ifconfig implementation fails to configure the tunnel device correctly. So you need ifconfig provided by busybox. Try a BusyBox Installer from the market.

The path to ifconfig is a compile time option to openvpn and can not be changed at runtime. This installer includes multiple binaries with preconfigured ifconfig locations.

The preferred way to install openvpn is to put busybox at /system/xbin/busybox and then choose openvpn preconfigured for '/system/xbin/busybox ifconfig'.

Finally /system/xbin/bb is not needed anymore! I hope this update makes live easier for some of you.

The all-in-one VPN tunneling, firewall & proxy bypassing, anonymization and anti-censorship solution

Is your Internet access being censored? Are some things on the Internet simply not accessible to you? Do you need protection from eavesdroppers or access without a login on an unencrypted wireless hotspot network or any other web-login based Internet access? Would you like to appear to be a user from a different country to avoid inconvenient content restrictions? Or would you prefer if your IP was not logged by every website you visit and everything you do logged by the NSA? Then look no further, you've found the solution!

Our Your Freedom service does all this for you, and more. It defeats censorship, it encrypts all your traffic, it hides your origin and identity, and it just makes things work that don't work without it. All you need is this app. There is a free service (called "FreeFreedom") available permanently to everyone who only needs occasional access and low bandwidth. If you need more, you can always upgrade later - once you know that it solves your problem and you need more than FreeFreedom provides.

Supported tunnel modes:

* HTTPS
* HTTP/POST/CGI
* FTP
* UDP
* DNS
