Can't syncing appointments 8wks back in my calendar

Hello-

My iCal on my computer is working fine...all meetings going back years and year appear just as they should in my calendar.

However, on my iPhone only the last 8 weeks of appointments appear.

There are items before that, but only ones that:

1. are recurring appointments

2. were invites from someone else

Any advice?

I'm not using iCloud, I plug in my iPhone 4S to sync it.

Am using iCal 4.0.4 and OS 10.6.8

Thanks!
