Yes, please! And make Safari more consistent with the OS X Version (gray, combined search/address bar)
While they are at it, they could make some of the icons cleaner looking.
I think the reason for the separated search/address bar is so that Apple can offer a different keyboard layout based on what text field you are in. If you are typing a URL, the keyboard is more laid out for typing in a URL, if you are in the search text field you get the classic typing iOS keyboard.
