Three20: waiting for better documentation

Well, I decided to leave Three20 on the side for a while. I'm not alone complaining about the lack of documentation for this library of classes. So I decided to convert my UITextField to a UITextView instead of using TTTextEditor. The result is exactly what I wanted: allow users to enter multi-line of text in this field.

How did I create the rounded frame around the UITextView? With PixelMator I took the standard UITextField box that I stretched on the vertical. This may be not optimal as I will have to create a version for the retina display but, for now that will do the trick.
