is there any way to mod the Cal so the week starst at monday, NOT sunday?

If your week starts at monday in iCal on your mac and you dock the phone, the event you import to iCal is imported to the day BEFORE the the acutual day (things on 11 jan on your iphone is on 10 jan on your mac!) i think this is because the week starts at sunday in you iphone

when iCal imports the events it doesent import by the date, but by the position.. week 1 day 4 is the 9th on your iphone and 10th in iCal (with week starting at monday)

some way to fix this!?

hope you know what i mean sorry for my crappy crappy english
