Issue with Contacts and deleting a contact in IOS7

A close buddy of mine got a 5c. He installed his apps but then removed Facetook. Facebook put his FB email in his Contacts. It's grayed out and IOS7 will NOT let him delete it. No delete option comes up? I don't own IOS7 or I would figure it out for him. Anyone here know what is up?

I'll take a look at it later Dennis. If I remember correctly, it can't be deleted on my iPad 3 running iOS 7.02 either.

He does not want it on his iPhone. Thanks Charley. Let me know what you find.

I just did some experimenting......

It looks like Facebook, Twitter, Vimeo, and Flickr once filled in or added to contacts can't be removed. I don't know if that's a feature or a bug Dennis. The way to remove Facebook is to do a reset with iTunes and then recover from backup. What the heck!

I had a funny feeling that was what it would take. Not sure why but my gut was telling me that!

Thanks, I will pass on the info to my buddy.
