As stated in the title of the issue, there is a call to window.history.back() in the click handler of jquery.mobile.navigation.js that causes a jump down to lastScroll of $to page AFTER the scrollTo top occurs before the startOut phase of the transition. This is one of the contributing factors to the jumpiness that is particularly noticeable on Android.

I have been using a fix I came up with for a while now without any issues. I'll be submitting a pull request either today or tomorrow for review. It passes all the automated tests, but may cause an issue on certain older platforms that I don't have access to in order to test.
