Everything was fine until today. I have an Iphone4s ( for a few more months ) and when imessaging, this weird box that looks like some sort of "capture" box appears when I want to type. I am going to add a photo. Also, my page seems to randomly appear bigger, cutting off the top of the screen, then go back to normal. But my real concern is the weird box on the imessage screen. Is it a setting I accidentally hit?
