The Nokia N8 has to be unlocked manually so that you can use it each time. It is kind of irritating. PocketLock is an application that locks your phone whenever the front facing camera is obstructed. It is kind of stupid when you’re playing a game and the camera gets blocked but luckily, theres a setting where you can choose when you want the N8 locked.
Its almost the same as a Blackberry, if you have a pouch that also has a magnet it it, the Blackberry gets locked automatically and when taken out of the camera, it deactivated the lock. In this case, if you tires of the N8 and want something that locks automatically, go for the Blackberries.
