How to sync Contacts after iOS 5.0.1 update

Issue: After iPhone 4S upgrade to iOS 5.0.1, iTunes 10.5 no longer synchronizes Mac Address Book with iPhone 4S Contacts using USB cable. iPhone Contacts disappear; Address Book remains intact.

iCloud: not used (it's unsupported on Mac OS X 10.6.8).

Carrier (cellular provider): Verizon

Solution:

Sync Services: Advanced troubleshooting for contact and calendar syncing

Article: TS2481

Skip the MobileMe section and start reading at the section:

For issues syncing contacts and contact groups in Address Book

I followed all steps except "Reset the SyncServices folder" and iPhone Contacts reappeared. The steps are well documented so I won't repeat them here.

Please post your experiences here.

Good luck, all.
