How to fix laggy video on iphone 4S?

My phone worked perfectly last night, and all the sudden this morning my video was extremely laggy to the point were I can't watch it. The audio is fine and it loads fast, but the video playback is so slow. I've reset my Wi-Fi, but that didn't help. The same thing happens when I use 3G. Safari is fine and everything else works perfectly, but it's impossible for me to watch youtube or any other videos online. How can I fix this? Or will it just go away on it's own?

Have you tried a soft reset ( Holding both the lock switch/ home button until the iphone turns off) ? If you have maybe try to visit your closest apple store.
