else having crashing problems iOS 5.1.0 update iPhone 4S

Hi, since the iOS 5.1 update I have been seeing alot of my applications crashing. Here are some of them that crash: Mail, Calender, Safari, and sometimes the AppStore. When I use Mail and try and send an email to others it will crash but it freezes first. Calender app crashes when I turn the phone from portrait to landscape. Safari just freezes and crashes at any given time. The AppStore also crashes when it gets stuck loading an app page... I have also noticed a few more bugs on the login screen sometimes I will try and press the numeric keyboard and it will not respond to me pressing the button. Then we have the keyboard sometimes exit out of its self when I am still typing... ;) Thats all I can tell for now..
