I donno if anyone else having this problem.....

I know iphone screen goes black when it near my ear while talking on the phone,
but still, the scren sometimes shows up because i move around my phone while talking... so the result is i always accidently touch the screen while talking...

is it possible to mod the system files and let iphone automatically lock the screen after answering or dail the call?

p.s. i know i can press the button on the top to lock the screen while talking, but its too trouble to do it everytime, so i think if there is a way to modify the system files and let it lock screen automatically.

Thanks
