I feel bad that noone has responded but on the crackberry mobile site there is only a link for apps not accessories so im not sure its even supported
^^ a little further down in the mobile forums section under 'stuff for your blackberry smartphone' there is a link 4 blackberry accessories. When trying to connect to that thru my bb, I get that 413 error mentioned above. So there is an accessories section.
