My iphone 5 won't unlock after i installed ios 7?

Hi, i have just updated my iPhone 5 to iOS 7 and now i can't swipe to unlock my phone. The screen won't let me slide to unlock nor will it let me turn off my phone…
Does anyone have a solution to this/experienced this with iOS 7 and can help me?
Much appreciated!

I have exactly the same problem. I can access the control center by swiping up, so the touch screen has not frozen completly, but I can't access anything within the control center, when I press nothing happens. The Phone will not repond when I try to swipe to unlock, swipe to the right for the passcode screen or slide to power off. Phone worked fine all day yesterday and this morning, nothing happened before this, no app crash or anything else.
Phone hasn't frozen as the clock is still keeping time. I have an iPhone 5 and iOS 7.
Will have to wait for battery to drain and power off then charge and hope it fixes itself I guess? Glitchy, seems so.iOS7.1 as soon as you can please Apple.

Hold the top on button, and the bottom round button for
several seconds to reset. Should be fine after that.
