maps

New guy to Pocket streets. recieved it with a new PDA :shock:
I have Pocket streets 2001 and can find no maps that will open in it, do I have to buy 2002 just so i can use this program??
Do you have to buy the thing every year?

You can use MapPoint on the web at http://mappoint.msn.com/ When you have a map on screen there is a choice: "Save to Pocket PC"
