I tested the Fixed Position toolbar on the Blackberry and it is not fixed, it is at the very top of the page and bottom of the page, as if they are not fixed at all. I tested the same on the iPhone on iOS 5 and it works great! As the Blackberry is listed in the "A-Grade" I am assuming the fixed toolbars should now work.

Let me know if there is any other information you need on this.

Fixes #3829 - BlackBerry 6 and below now default to native position: …
…fixed toolbars, rather than being demoted to static positioning.
Native position:fixed support in BB5 and 6 is pretty slow/buggy so we had excluded these from seeing this CSS rule but we've reversed this decision and let BB do what it does even if it's not ideal.
