One thing I don't like

In the messages app, if you write a long message it will go right to the top of the screen rather then just three lines. This means you can't see any of the previous messages and is really annoying, i can understand it in the landscape version as there is a lack of space but i don't think there’s need for it in the portrait version. At the very least give us a button to temporarily drop the keyboard so you can have a quick look at the message you're replying to like twitteriffic does.
