IPhone :: Its Slow After Updating To IOS 5.1

I have a 32GB iPhone 4 with about 2GB free and recently updated to iOS 5.1. It has become noticeably slower since updating it. There are some short delays with certain apps, some have become jerky and the Home button isn't as sensetive as it used to be. But the worst part is the camera and the photos app. The camera takes For to load before it's ready to take a picture, and switching to video takes even longer. I've waited up to a minute before either one is ready for use and sometimes have to wait 10 seconds between shots! Also the Photos app has become really buggy and will sometimes crash, especially if I try to edit a picture. This is not cool. I've tried turning the phone off and on. I've tried resetting it (Home+Power buttons). Next I'm ready to try throwing it in a bucket of water to see if that might work.
