I own a new BB7290 and - of course - I'm looking to expand its possibilities.

1. Anyone with ideas about what should I start with?
I've just installed (trial version for starting) of eOffice and some messenger applications. While the eOffice stuff is working just fine, I couldn't have the messenger work (the message is "could not open tunnel - failed" in all cases). After some search on the forums, I understood that I should look for some APN settings, in order to have a direct TCP connection. Any bright ideas about how to do that (network operator: Orange Romania)?
Thanks!
