The reason you are having so much trouble is because you have your device set to send/recieve email so often. Set it to auto send recieve every hour or more then you won't have so many freezes. It is freezing because you are probably using an app that requires data and while you are trying to do something your device is trying to send/recieve email and things slow to a crawl.If you want to check your email more often check it manually.
