Which provider do you have?
If it is VZW and if you wanna do the actual exchange server I am unaware but I believe you can through
Wireless Sync. It allows you up to 3 "corporate" emails which give the option for Exchange server. If you already have a data plan with VZW with WS program is free. Just set it all up and you should be set. For trouble shooting refer to their WDTS department...
