What's going on with the header?

That's the thing I meant but had not the vocabulary to describe- with a touch screen device like an iPhone/Android/HTC Touch etc the new location is too close to the edge of the screen, meaning that when one goes to click on it you get the wrong thing 80% of the time, as opposed to previously when it was easy to use the breadcrumb trail to navigate back and forth.

With the new location I now go back to the main menu then back into say "General", which takes more time, uses more bandwidth and emits more CO2 which is doubtless killing another polar bear whenever I do it.

For shame Velocio!

I'm not really a fan of polar bears. If they'd evolved white noses I'd have more respect for them as a species. Then they'd be an iBear and we'd have convergence of the conversations.

I'm happy to make changes, but I'm stuck in a catch 22.

Not being an owner of an iPhone or android phone I cannot see what you're seeing. And not being able to make rapid changes and test them I cannot begin to 'fix' what you perceive to be the issue.

All I can do is look at the page in FF, Chrome, IE and Opera and hope that every other browser and interface out there does the right and renders it in a meaningful way.

If you want to lend me your iPhone for a weekend so I can test, edit, test, edit, etc... then cool. But without your specific thing for me to work against, I simply trust that the iPhone isn't a piece of crap and will do the right thing.
