Kinda embarassing but I've only had the phone for a week so bare with me. I got the phone jailbroken (I love pwnagetool) but I am having trouble syncing new contacts I've added on my iphone back to my mac's address book. Everyone says it should automatically pick up which contact list is the latest when you sync address book in itunes but it's not, luckily my address book has all but one new contact. I am wondering if there is another way to tell the address book to update using my iphone's contact list without manually putting new contacts in myself?

I currently own the iphone 2G. If anyone can help it'll be great.

you need to setup iTunes
first connect your iPhone and select it in iTunes
click on the INFO tab
check the boxes that say "sync Address Book", and "sync iCal"
