I also took the G1->Milestone path.
I am equally surprised that according to Motorola, the Canadian Milestone is NOT a quad-band phone or world phone as they are sometimes called. I am wondering if that is a mistake on their site.
Have you had any success with T-Mobile Visual Voicemail? That is the one thing that I am having trouble with T-Mobile-wise. Their support wishes to not provide any assistance because the Milestone is not one of their phones, however the problems it is exhibiting were there on the G1 when I first configured it for Visual Voicemail. (I know I can configure Google Voice in place but I wish to keep the two mailboxes separate). I have a thread going here with my experiences so far:
Motorla Milestone ( GSM ver. of Verizon Droid / A... - T-Mobile Community
If you haven't tried could you test and let me know?
