I got BBM on my n900 sort of
I installed Impatica viaDock on my desktop so i can control my bb from my pc. i installed vnc on my desktop. so i can take control of my desktop with my n900. thats the closest i got to get bbm on my n900 lol..
it would be a lot nicer if there was vnc server for blackberries .
or even better if there was an app that makes u directly connect to the blackberry and also get incoming notifications.
