Please excuse the iPhone noob question. On my EVO I was able to hide the keyboard on any screen by tapping the back button. Is there a way to hide the keyboard on iOS when done typing? For example: Lets say I'm composing an email and I'm done typing but want to read it before I tap "send". I see no way of hiding the keyboard so you have more screen real estate to proof read your email. I see that you can hide it if you're composing a text message by swiping down but not on any other screen where you use the keyboard. Or am I missing something simple?
