N900 has never been into a perfect portrait mode so thats why some time even with cssu updates things go a bit up n down ,anyway cssu is working so hopefully soon we ll be having full working portrait mode.
swipe,chosen for N9,i am looking for its direct port as if it is open sourced.
and if not then ,i would love themes which will unlock screen by taping my finger tip from top to bottom in portrait ..waiting
