Is there a free or at least a free to try Jabber IM client out there for the Blackberry? We currently have a jabber infrastructure in our company now and i would like to utilize that on our devices... I can't use Google or anything like that which requires the data to go to the outside ""Public" world. I need it to stay in house just like our current Jabber to Jabber does now on the PC's.

Thx
