UTStarcom PPC-6700 / XV-6700 / HTC Apache

because Bill Gates didn't want it to, seriously though WM phones do not set automatically. Microsoft decided on that.

Go into Settings, Phone options, Services tab at the bottom and look for Time Synchronization. Highlight it, hit Get Settings and there is a checkbox for whether or not to sync with the carrier. Works fine on my VZW XV-6700...
