I just activated unlimited as well. I've had my iPad for almost 2 weeks now but for some reason I didn't realize until today that the iPad mail program could sync with my work exchange server (I currently use a BlackBerry). I decided since I usually have my iPad with me when I'm doing business I downgraded my BlackBerry plan from enterprise to personal and added the unlimited plan for the iPad. I also have an almost 3 year old MacBook Pro and just now realized I could sync iCal, address book, and mail with the exchange server as well. Lol.
