iPhone won't turn off and won't sync even after I plug in my computer.
My iPhone started acting odd after my husband updated it to iOS5. It started with when I touch the apps, it responded with delay. Today, when I want to check my email. The app just simply not responding to any touch on the screen. I tried to turn off to restart, but it won't turn off. So I plug in my computer try to sync see if that can somehow makes it "budge". I successfully upload the new photos from iPhone to my MacBookPro, but after that, it won't "sync". The "sync" bottom on the itune page stay "gray". I cannot click on it. What should I do?
iPhone 4, iOS 5
