I don't know if it is the same problem, but I've got a Dell e6500 with built in 3G, network-manager in Jaunty recognizes the card and is willing to configure a "Mobile Broadband" network for it.
When I try to connect to it, it tell me it couldn't, yet, if I look at the logs, I see it authenticate and get an IP address, and then it disconnects.
If I use wvdial from a terminal, it connects and works !
