I recently undertook a (failed) journey into synching my Gmail contacts with my Address Book. The end result was much annoyance, followed by a day (ok probably 20 minutes) of cleanup to get my list back to normal. FINE. The cleanup got done – I re-synched with my iPhone and viola: contacts restored to normal… or were they?
10 minutes later I received a text from someone not in my contacts list. Upon further inspection, it was a good friend of mine (who I frequently trade messages with) — what the heck? His number isn’t in my address book?
A quick check of my laptop revealed that he was still there but wasn’t properly being synched to my phone. It wasn’t just him – 25ish contacts were mysteriously not showing up properly. Editing individual entries and resynching got the job done but finding these 25 people was really getting annoying – I needed a truer solution.
iSynch -> Preferences -> Reset Sync History
That, plus one more “synch” through iTunes – and I was back on track. Hope that helps if you’re in that same boat!
