Can’t Connect to Mobile Broadband Access

Brand new Omnia and it looks nice but I haven’t been able to connect via #777 to "boradband access" very often, and when I do, it’s quite slow. At the moment I can’t connect at all. No internet, no email, no nothing. Nada.

Nice phone, though. Any idea how you’re supposed to connect to this mobile broadband access? 

Thanks.
