iOS 5/4 issues with white gap on left.

[cheerfuloriole]

This is my first time creating an 'issue' on Github. Hopefully I did it right. Here goes...

When clicking a navigation item in the slide menu my main page would slide in. Good. Then I would click a link within the main page which would slide in another page from the right. Great.Then I clicked the back button, to go back to the main page. It would go back...kind of, but there would be a 240px white gap on the left .

On jqm.slidemenu.js I changed...

$(":jqmData(role='page')").css('left', '240px'); 

to

$(":jqmData(role='page')").css('right', '-240px');

and now it works on iOS 5.1 and 4.0.
