Applescript for making all-day events in one calendar (iCal)

Hello all,

This is a kinda long story… Well, it started when iSync didn’t support full-day events with the Sony Ericsson T610. So I used the All-Day Fixer. This adds a new calendar in iCal and deletes the fuill-day events, so iSync can send the events to the T610.
But since iSync 1.5 iSync actually DOES support all-day events… So this means I have to change all the events to ‘all-day’.

Could someone make an AppleScript that makes the events in a preferable calendar to all-day events? If so, I would be really thankful.

Thanks in adavnce,
