Many built-in IB elements have a separate "layout" versus "bounds" rectangle. You can see the difference by showing them using the "Layout>Show XXX Rectangles". The drop-down indicates which rectangle the coordinates refer to.

On Mac, this impacts UITextFields that are labels for example. If you switch between Layout and Frame, the X coordinate will change by 3 pixels. I haven't played with iPhone controls to see if it impacts any of them. It doesn't come up a lot.
