REA synchronizes with Outlook 2003 or 2007. From there, you have to synchronize to your smart phone, be it Treo, BlackBerry or whatever. Exchange server has tools that your IT department can activate-if you have an IT department. If you do not have an IT department, you can use install software on your computer and do it yourself.
My favorite synchronization software is a product of Companionlink Software. They have been doing this stuff for a long, long time and are the best. You can download and try it before you buy, which you should.
