How to use Jimm with Blackberry Bold via WLAN connection?

[S.H.]

Hello,

I have searched for a messenger program (ICQ) which I can use via the WLAN connection on my Blackberry Bold.
Therefore I wanted to try out Jimm but I got stuck at the network configuration.
No matter what settings I apply, I always get an error (sometimes 120.0, 115.1 or something like this).

So Was anyone able to establish a connection via WLAN on any Blackberry phone?

Thanks a lot.
cheers

I'd be grateful for such solution as I have also received several requests for this usage of Jimm (through WLAN connection). Anyone?
