I think about this while im driving and needed to change the music, the device was locked and it annoys me to press the unlock key

the idea is:

we catch our locked n900, hold it like portraid mode,with the screen on top, horizontaly, and turn 180 (screen down) and return back 180 (screen up) and the th.e device is unlocked....

its like turning a key locking and then unlocking...

it like when we wanna put the alarm in snooze, we put the screen side down... but in this case the device unlock when the screen returns to up...

this exist for our device?????

thanks
