Connect it to your comouter, open up your itunes, make sure itunes read up your phone and you can see the name of your phone in itunes, don't do anything, just leave itunes open while iphone is connected to your itunes for a while, 10mn. Disconnect your phone, softrestore (power button and home button) use your phone and the issue should go away.
