Actually this problem will be arises when you will put off the battery from the iphone. Date & Time will be changed. So set your time manually or with the automatic settings using wifi. Problem will be solved. I had the same problem today.

But still I have another iphone. Which has the exactly same problem. I couldn't solve it on that phone. There is an another problem with  "wifi button greyed out" I mean disable. wifi is not working right now. So how can I solve these problem for the second set.
