Problems with WP blog layout on mobile devices

I am having a problem with my WP blog. When viewed on my desktop Mac, it looks great. But on my iPad, the right sidebar is partially cut off, with text and images bleeding right to the edge of the screen. On my iPhone, the entire right half of the blog is “missing.” I’m using the Brunelleschi theme, specifically a “no collapse” child version which retains the sidebar when viewed on mobile devices (which is what I wanted). Pinch-to-zoom also doesn’t work on either for some reason although it does on virtually any other non-mobile version web site I’ve looked at in Safari. I tried the Opera mobile browser too, but same thing.

Is it an iOS 5 bug? I have the latest version of as yesterday. Is there any way this can be fixed? I could use the default mobile layout with the sidebar content below the posts, but I’d prefer to keep the same layout as on the desktop.

Thanks,

Paul
