iPod Touch 4g internet conection works on and off

I got my new touch just a while ago after my classic died, it worked great. Then out of the blue the internet performes horribly. 99% of the time now I get the error that I cant connect to the itunes store or appstore when I open it. If I can get it to open and download something; it fails instantly saying cannot connect. In safari the internet is meh, sometimes it wont open certain pages but does a lot better than the apple store. My email works fine. When Im one facebook however if I try to view lots of images after the first few it will say no internet connection, my newsfeed seems to work okay though. My other apps that use internet are also kind of glitchy but some work fine while others dont work at all. I have no idea what is wrong. I tried a restore and the ios upgrade and a bunch of other stuff. It is not jailbroken if you are wondering. I am also having more app crashes now and i have light leakage in the right bottom corner. Anybody know whats going on?
