Help needed!!!!!!

Ok, so, today, I got iOS 7 for my iPhone 4. The screen completey F***'d up, I don't have a clue what happened to it. I left it for a while and it was fine again. But the outskirts of the screen is still F***'d up. I think it's the inner screen that is F***'d up. So, I thought restoring the iPhone 4 would make the fuzzyness of the screen go away. My phone restored and now it wont activate, at all. I went past the 'choose a network' stage and then after that I clicked next and this is what comes up



'it may take a few minutes to activate your phone'



but then it says this



'Your iPhone could not be activated because the activation server cannot be reached. Try connecting your iPhone to iTunes to activate it , or try again in a few minutes'



I connected it to iTunes and it said 'we could not complete your iTunes store request. The network connection was reset. make sure your network connection is active and try again'



My connection is fine. And as for the screen, it looks like all the colours are swirling around the screen. I don't know what caused any of these problems.



If someone could help me, then, that would be greatly appreciated



Thanks
