The viewport in alpha4 isn't resizing at all after an ipad/iphone (ios 4.2) rotation.

Everything is fine on android.

The problem arises when height=device-height is used with width=device-width in the meta viewport. Is this actually the right behaviour or is it a bug?

Alpha4 also suffers from double tap problems that have been solved in beta-pre.

The whole virtual event thing seems to be buggy in beta-pre, for example:

        pagebeforecreate event is fired before a 'vclick' event bound to an anchor. The normal "click" event is correctly fired before any page-related event
