How does jQuery mobile hide mobile safari's addressbar? I think I need a similar solution, but i don't want to use jQuery mobile ...
I tried:
http://davidwalsh.name/hide-address-bar
but that doesn't work in my case.
My first child of the body is an absolute positioned div
with -webkit-overflow-scrolling: touch;
The -webkit-overflow-scrolling property seems to cause this problem,
without that property it works fine.
Part of this problem is the address bar always stays in foreground, even if I scroll the page down per hand. this is caused by the absolute positioning.
But, without absolute positioning, "-webkit-overflow-scrolling: touch;" doesn't work ...
After a big fight with thousends of lines jquery-mobile code, i ended up with this ;)

FINAL EDIT, SOLVED
It has nothing to do with -webkit-overflow-scrolling, but rather your height: 100%. (Don't know why I missed it before).
The only difference between your file is the <meta> tag changes outlined below and commenting out height in the CSS.
Tested on iPhone 4S/iOS 5.1.
This is what we use:
window.addEventListener("load",function() {
setTimeout(function(){
window.scrollTo(0, 1);
}, 0);
});
It works everytime.
And we only use addEventListener since the only phones we care about are webkit based...
Your -webkit-overflow-scrolling div shouldn't matter here. Have you tried placing it 1 pixel down on the page? Regardless, any scroll down should just cover the top pixel of your absolutely positioned div.
So I loaded one of your examples and this is popping up in the error console: (this doesn't fix the issue, but...)
Viewport argument value "device-width;" for key "width" not recognized. Content ignored.
/dev/1/:7Viewport argument value "1.0;" for key "initial-scale" was truncated to its numeric prefix.
/dev/1/:7Viewport argument value "1.0;" for key "maximum-scale" was truncated to its numeric prefix.
Looking at your <meta> tag I see:
<meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0;">
You need to use a , not a ;
<meta content="width=device-width, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no" name="viewport" />
