Since the upgrade to iOS 5 I have been experiencing a large number of app shutdowns. It happens in Apple apps, like Safari, and in third party apps, like games and weather apps, etc. anything seems to be vulnerable and it is getting irritating. It is happening on my iPhone 4s, my iPad 2 and 4th generation touch. It's also happening to my wife and her devices. She has an iPhone 4 and doesn't want me to upgrade her iPad because of it. Anybody else noticing this?
