I had that problem with Sprint TP, and I hated it. Now I have the TP2 and HTC is trying to complete envelope WM with it's own custom TF3D crap... now the calendar only displays in day or month view--no week, or no year!
I actually used year view, as I would scroll through years quickly in year view and then enter people's birthdays on the exact day, month, and year they were born. It was cool, because after marking it as recurring from that date onward, the calendar would display the recurrance in parenthesis each year. It helped me remember how old my old parents were
So far, I haven't found a tweak to the TP2 calendar yet...
Thanks, mikel81 for the link. Too bad I didn't find this when I had the TP.
