White space at bottom of the page in iphone

Hello,

I have a jquery mobile webpage. It looks good on desktop browsers, and also on android.

But in iphone's safari, I have a weird white space in the bottom of the page. It looks like a problem with the min-height of the .ui-page, because the white space is as height as the title-bar + url-bar of safari.

Please have a look on the screenshot attached...
