Club i-mate has registered its 500 000th member today, making it the world’s largest Microsoft Windows Mobile user community, the company announced today.

The Club i-mate Web site essentially provides tech support as well as features, utilities and applications to accompany members’ i-mate devices. In addition, every owner of an i-mate device gets a Hosted Exchange email account.

To celebrate the milestone, i-mate is offering four limited edition red i-mate JASJARs in an online prize draw at www.clubimate.com for four weeks to members from today.
