I am currently on BES, although I can't SSH/TELNET to servers located in our datacenter, nor can I access servers within our local network. Not sure why!
I am currently using MidpSSH and when trying to connect to a server I get the error message: Session Error - Newtork is unreachable: connect.
My wife has a Curve and I did notice VPN option in the Wifi settings tab. Just thought this would be available for the 8800, as well.
