yes beejive is free and its pretty cool there are still bugs in it that they are working out hence jivetalk BETA!!!! check out
www.beejive.com and go to the windows mobile beta its a cab file so you can install it directly onto your phone. and once installed it asks do you want to activate click yes. for me it kept failing to register and wouldnt work until i did a soft reset but it works wonders now!!!!! enjoy man
