Left, Right, Up, Down

When operating my home Media Center PC from my phone, Windows MediaCenter moves between menus with the up, down, left, right keys. With the standard iPhone keyboard, there is no up, down, left, right keys.

what about adding these where you have the esc, ctrl, alt and F1-F12 keys on the tool bar within the app that you can launch. These too are keys that the standard iPhone keyboard does not have but we need these up, down, left, right at times too. That would make a really nice update to the iPhone app since iOS doesnt believe in these keys.
