PIN entry UI after iOS 2.1 update is very unintuitive

The new PIN entry screens after the 2.1 update on iOS seems very poorly laid out to me. It places the ‘Log Out’ button right below the input field while the ‘Unlock’ button is much smaller and at the top-right of the screen.

Can this be swapped? The ‘Unlock’ button should be the largest, most obvious, easiest to reach from the keyboard button since it’s the one that will be used 99.99% of the time.
