The AstraSync™ BlackBerry App is a fully licensed Microsoft ActiveSync application for BlackBerry synchronization used by tens of thousands of BlackBerry® smartphone owners worldwide. AstraSync performs two-way over-the-air synchronization of email, calendar and contact data with any Exchange ActiveSync compatible server.

This BlackBerry software runs without the need of the Blackberry Enterprise Server installed on your mailserver or enabled on your Blackberry account at your carrier.

AstraSync™ has been tested with a wide variety of devices from the most popular carriers, including all of the most recent BlackBerry Phones such as the BlackBerry Torch, BlackBerry Curve, BlackBerry Bold and BlackBerry Storm models. AstraSync does not work with OS version 4.1 or earlier.
