I've never used FaceTime before, but when I went to try it on my iPad 2, I saw a lot of recent calls. I want to delete them all at once, but I don't see an option in settings for recent calls. I'm guessing that they were calls to my iPhone, but I've deleted all recent calls from there and yet they still appear on my iPad. I'd also like to know how to prevent this from happening in the future. Thank you.
