When trying to sync photos between your iPhone 3G and your Mac, you get an error:

The iPhone “Name’s Phone” cannot be synced. You do not have enough access privileges for this operation.

To resolve this issue, you will need to delete the iPod Photo Cache file on your Mac.

1. Go to your Pictures folder (~/Pictures).

2. Hold down the Control button on your keyboard, click the iPhoto Library file and select Show Package Contents.

3. Locate the iPod Photo Cache folder and delete it.

Now try to run through the sync process. Hopefully it works now.
