I have a question about skype/msn. Is it possible on a blackberry to have voice conversation through skype or msn with a contact being online? If so, is it possible for 2 people using a blackberry to be on msn/skype and have voice conversation via the data plan and it being free? because, we will be using the internet and msn/skype to talk to another person who is using da internet/data plan on their phone. For eg. when i am sitting on my pc and another person is on their pc, it costs nothing to have a voice conversation.

AFAIK, there is no SKYPE app for the BB. Plus EDGE doesn't have the bandwidth to support a decent VoIP or similar call and the BB 8700 doesn't support 3G.
