I did a quick search for this problem I've been having but came up empty. Since updating to OTA 2.1 I've been having a random Facebook contact come up when I hit Phone- where it shows received, dialed or missed calls. It has the correct phone number, but always the FB picture and name of this guy Don, whose number I don't even have. The correct name, picture and phone number will come up when the phone rings, but after the call is ended, it shows up in the call history as this "Don" character. Only way I know to change it to the actual person is to re-start the phone. Has anyone else experienced anything like this??
