Merge your Gmail and iPhone contacts

Merge your Gmail and iPhone contacts
Once the iPhone contact information has been added to your Gmail contacts, open the Gmail contacts list and click More actions > Find & merge duplicates. Any redundant entries the scanner locates are displayed with links for more details. Click Merge to combine all the duplicates at once.Use Google Contacts' automerge function to clear duplicate entries prior to syncing the list with you iPhone contacts via iTunes.Screenshot by Dennis O'ReillyAfter the duplicate entries have been excised, review the contact list to spot any double (or triple or quadruple) entries that automerge may have missed. In my case, 23 duplicate entries were merged automatically but about a half-dozen other dupes remained. To merge these manually, check their entries in the main contact list and click More Actions > Merge Contacts.When you're satisfied that the Google contacts are in order, return to iTunes and run the contact-sync option again to copy the newly trimmed list to your phone. The contact entries in Google and on your iPhone will then be identical, or as close to identical as the two systems allow.
