Can't Delete Local iPhone Calendars

Question

Has anyone else had issue with being able to delete local iPhone calendars.  I have about 5 and I need to delete 3 of them.  I open calendar, click the Calendars button in the top left hand corner on the iPhone and then edit and open each calendar and delete.  It deletes the calendars events but then under the calendars it still lists it as a calendar?  Very weird, I have tried it 100 times and it never deletes the actual calendar, keeps it in the calendars lists, just deletes the entries.  HELP?

The problem is solved.
The command that solved the problem was:
*sudo chmod -a# 0 ~/Library/Preferences/*
The brief shell script that diagnosed the problem was:
#!/bin/sh
*ls -l@ed /*
*ls -l@ed /Library/*
*ls -l@ed /Library/Preferences/*
echo
*ls -l@ed ~/*
*ls -l@ed ~/Library/*
*ls -l@ed ~/Library/Preferences/*
*exit 0*
The problem arose when a calendar event was copied to the clipboard, then pasted back to a different day, during an iTunes 7.1 software update.
