Sync Contacts with iPhone

Contact syncs are bidirectional....changes, additions, and deletions you make on the iPhone should be reflected on your computer.

In the iTunes Info tab, make sure you don't have the Advanced settings to overwrite the phone checked.

The sync process with Address Book contacts, iCal calendar events and Safari bookmarks is bi-directional or should be.

My contacts sync in both directions.

I'm having a bit of trouble with this too. After selecting my iPhone in iTunes the info tab has that Advanced setting which indicates that on the next sync a "replace" info sync will happen. However, that doesn't seem to happen with a few of my contacts.

Am I misunderstanding the way that Advanced setting is supposed to work?

Checking anything in Advanced overwrites ALL info on the iPhone with what is on the Mac or PC.

This is not something you want to do if you manually put in allot of Data as this would be overwritten.

Your best method would be to go to iTunes Preferences in Windows- iPhone Tab- Reset Sync history and try and sync again.

or on a Mac open iSync in Applications. Then open iSync Preferences and Reset Sync History and test again.

I don't know why this worked, but it did.

Thanks!

Not a problem. Glad I could assist 🙂

Thanks! I had the same problem I could not sync in my iphone and address book (bi-directional) it would only sync from phone to address book. The problem started when I had my phone replaced. After following your method of isync reset all is well now!
