TouchDown provides push email for the T-Mobile G1 Android device

TouchDown has filled a major void in the Android space for me personally and with the full push functionality and Exchange syncing capability I can now use my G1 as a daily phone if I desire where before it was primarily a hobby phone. At this time, the push functionality is available to those who are signed up the beta versions, but it will be available soon as a free upgrade to the commercial product in the Android Market for all licensed users.

In addition to the push technology, the ActiveSync license includes security related features such as PIN enforcement, prohibiting databases from being placed on the microSD card, and remote wipe capability when used with a server that supports it. These security features may aid in the consideration of the platform by companies concerned about security.
