Kaiten is an excellent email client for Android phones and tablets.

Kaiten Mail is an advanced email client for Android. Based on the award-winning K-9, Kaiten has been completely redesigned to look gorgeous on your tablet. (It looks pretty snazzy on your phone too.)

Kaiten supports IMAP Push, POP3, Exchange 2003/2007 (with WebDAV).

Kaiten supports multi-folder sync, flagging, filing, signatures, bcc-self, PGP, mail on SD, multiple identities, search, configurable notifications & more!

Built by K-9's lead developer, Kaiten is simpler, easier to work with and a whole lot prettier. Frequently used commands are now available in the application's action bar. If you have the screen real-estate, Kaiten's split-screen view lets you see a mailbox and individual messages side-by-side.

If you're having trouble with Kaiten, drop me a line and I'll do everything I can to help you out.

Please note that neither K-9 nor Kaiten Mail currently support Exchange ActiveSync.

Kaiten's name is a play on K-9. It's a Japanese word that means rotation and sounds a lot like K10 or K-10.

SSHTunnel is a SSH tunnel app for Android System, based on Connectbot and Dropbear / OpenSSH (Beta Branch). With this app and a configured server (typically configured with sshd and nginx / squid), you can easily browse internet through a SSH tunnel on your android devices.

This keyboard is especially useful if you use ConnectBot for SSH access. It provides working Tab/Ctrl/Esc keys, and the arrow keys are essential for devices such as the Xoom tablet or Nexus S that don't have a trackball or D-Pad.

There’s built-in OpenVPN GUI in CyanogenMod since v4.2.15 and it’s poorly documented. When adding new VPN connections you have to tell which key you want to use and you can’t load anything from files. You have user.crt, user.key and ca.crt files generated with OpenVPN’s easy-rsa scripts. You can’t use them directly, you have to bundle certs and key into PKCS12 file. Here's how.
