iPhone 4s, iOS 6 keep asking me for my Apple ID password
Hi,
I have updated my iPhone to iOS 6. The problem it keeps asking for my apple id password. I can either click cancel or fill the password, it works just fine but will pop up again. First I tought it was related to one specific app (LINE by NAVER) but not always. I have tried google for answer but had no luck. Any idea? I deleted the LINE app, and reinstalled. I even restored the phone but nothing helped.
