HTC Mogul / XV6800 / PPC6800 / P4000

I have had this phone for a week now. I want to like it....great reception, decent speed on EVDO, I JUST CAN'T GET IT TO F'N SYNC! I have been working with SPRINT several hours a day with no luck. I have been resetting it so often I can't make myself enter contacts or use as a PDA 'cause I know they will get erased every day (same for music). I get the following error messages
0x80072EDF
0x80072EFF
and I think I even got 0x80072ESF.
Anybody got any ideas????
