This post is from a previous deal, but has been updated to reflect the new price!

If you're the corporate type and have had some issues with Android's default Exchange compatibility, then you've probably looked for a good alternative. Among the contenders is an app by NitroDesk called "Exchange By Touchdown," which allows for secure, encrypted Exchange synchronization.

You can only get this deal in the Amazon Appstore. It's still $19.99 in the Android Market!

Touchdown works with any Exchange Server that has ActiveSync enabled, all you have to do is enter your email login credentials. It offers encryption for email fields that may contain sensitive data, as well as calendar and contact entries. It also encrypts any file that is downloaded the SD card and renders the file unreadable if the SD card is removed and put into another device.

Also included in the package is a remote wipe feature, which can either be initiated by an administrator, or, in the circumstance that you're not using ActiveSync or don't have administrative authority, via email.

Note: The remote wipe feature only wipes data associated with Touchdown, not the entire device.

There is also a thirty day free trial in the Amazon Appstore, so you can give it a go to make sure it works with your setup before you shell out the cash. Be aware, though, we're not sure how long this deal will last, so once you find out that it works correctly, you may want to go ahead and jump on it while you can.
