All, I have an iphone 3GS with updated IOS4 software. When I enter a text message conversation, the phone displays the conversation on the full screen. If I tap the new message bar, the keyboard pops up as expected. the problem is that I can't get rid of the keyboard once it is displayed. This is frustrating because most of the message thread is cut off due to the keyboard. How do I get rid of the keyboard if I just want to read the thread and not type a new message?
