Nokia N80

I've been reading on other forums as well as this one that a drawback on this phone is the slider function does not have a spring mechanism so that it "locks" or snaps in place when sliding. This could also cause the slider to move while in your pockets and automatically dialing numbers.

Can't you prevent that by hitting the main menu button (middle button on the 5 way navigator button and then pressing *

That locks the keypad and prevents inadvertent dialing.......
