I was looking up a contact using the search feature, search didn't find it even though I know it was there (have it on my iTouch). When I deleted the search terms (backspace until empty) all of my contacts were gone. I exited the app and went back in (figuring the search may have confused the app), still all gone.
Anyone else experience this?
If I resync with iTunes will that restore everything, or will it wipe out the contacts on my Mac?
Are you a MobileMe customer? Do you sync your contacts from a PC or Mac?
One possible solution is to restore from a backup in iTunes where your contacts exist, then 're-add' anything which is missing. It's a chore, but contacts wouldn't just disappear like that usually.
Hope I helped.
