i've been with a pc all my life till this past may. i finally restored and formatted my iphone 3gs to my new mac book pro in preparation for iphone 4.

however, before deleting it all on my current iphone, i saved all my pictures and videos from my camera roll.

my questions is: how do i save those pictures into my newly (mac) formatted iphone?

hope the question makes sense...i just want to have my camera roll full of the hundreds of pictures i've been taking with my previous iphones on my current iphone since i had to delete it all when formatting it to a mac.
