Seems like you should install testing. At least that's what helped my N900.



I find portrait to be awesome but there's one flaw with it. I think that the menu button should be relocated (if possible) to improve the ease of using the phone in portrait. I find it quite hard to press menu button while using only my right hand. It would be awesome if it was at the bottom of the screen (only in portrait - in landscape it doesn't matter since it's optimal to use both hands) or at least at the top right corner. But I'm afraid that it would require rewriting the whole portrait mode from scratch :/.
