touching the status bar simply scrolls all the way up. It is made to
show the URL bar.
Refresh arrow refreshes the page. If there are no changes it doesn't
"change".
The go button "opens" the url inserted therefore actually fetches and
displays the page.
I doubt you would be able to hide the url bar since Apple wants to
provide a way of doing so.
Unless you set a timer/interval that check the current display and in
case (if the user didn't already scroll down) make sure that it's at
(0,1).
