Daved,
Are we having the same issue? I'm trying to get VoIP running on WM6.1 but I don't see the Internet tab listed under Start-Settings-Personal-Phone.
Under the Phone menu I only see Phone, Services, and More tabs. ‘Internet’ isn't a tab listed at the bottom.
I posted a thread here:

let me know if it's the same issue for you. It's driving me nuts.
