We have assurances that "If you see a task manager, they've failed." But, in fact if you run your iPhone 4 along for a while, eventually you will find you can't see emails when you open them. The solution? Open the dock by two taps on the big round button, then hold down an icon till they all start to shake, then tap the "x" on each one in the dock till they all have disappeared. You have just used the nonexistent task manager to quit them all and free up the memory to make your iPhone on iOS run right again.
