contactsicloudiphonerestore
I honestly don't know what happened, but it appears that I lost a number of key contacts out of my address book. I didn't delete them manually, but regardless of what the cause was – they are gone.
Is it possible to restore contacts back, say from a few days ago?
Additionally, and this might be symptomatic of a bigger issues, some of my contacts appear in duplicate.
Please help
If you want to just clear the birthday field programmatically, you could do that on a Mac that syncs contacts with the iPhone (either via iCloud or iTunes).
Open up AppleScript editor, paste in the following and hit run to clear every birthday in your address book.
tell application "Address Book"
set thePeople to every person
repeat with thePerson in thePeople
set the birth date of thePerson to missing value
end repeat
save
end tell
If you have the birthday data already in some other format and are looking to import it, that could be done, but would be a bit trickier. You'd probably need to get the AppleScript to look up the birthday for a given person from a file. If you need something like that, please edit your question to be more specific and give some sample data if possible.
I'm not sure if this will solve the problem exactly as you specified, but you can hide those 4000 contacts of customers on your iPhone with the steps below.
If your entire email's contacts are synced with your iPhone, you can choose to display only actual contacts and hide those email contacts with the Groups button in the Contacts.app in iPhone
For instance, this is a sample screen that could show when you touch Groups
Also, if you go to your Mail settings on your iPhone (Settings => Mail, Contacts, Calendars) and your Mail account, you can choose to remove your email contacts from your iPhone contacts by turning Contacts off in the picture below.
