Hey guys this looks old but Ill throw my problem in here,

Trying to sync my 1st gen. iPhone with iCal through iTunes. iTunes sync pictures, videos, music, programs, podcasts and everything perfect, but not my calendar, i select "sync iCal calenders-all calenders," and then in the advanced settings i select "replace info on this iphone unit", and select "calender"...

now, when i select "use" in the lower right corner the advanced setting "replace info on this iphone unit" just unchecks "calendar" and my calendar on my iphone is still empty..

what is wrong? how can i fix this?

-Thanks
