I have a client that has a Blackberry from TMobile. He wants to sync it with Exchange 2010. The IPhones and Droids have an account manager for setting up activesync with Exchange. Blackberry does not. They seem to want you to subscribe to their Blackberry Exchange Server. I have heard that there are 3rd party applications you can download for Blackberrys that will setup activesync. Does anybody have any recommendations?
