The iMate JAM is a wonderful device and has been hugely successful in Europe!  http://www.clubimate.com/t-DETAILS_JAM.aspx 

Interestingly in trying to discover what the new JASJAR acronym meant - I found out what the JAM meant :)

Considering that the device looks suspiciously like a certain white music player I presumed Jam was relating to it's music capabilities....

I was wrong....

JAM stands for Jim Andrew Morrisson

Jim Morrison is the CEO and Founder of iMate and prior to that Jim was Head of Mobile Device and Application Development for BT and BT Cellnet Limited (now mmO2) leading 2G, 2.5G and 3G product and application teams.
