Emergency Icon in DOT unlock screen

[beasttopray]

I have the Samsung moment, Android 1.5 OS .I was wondering if anyone had any idea on how to remove the emergency 911 icon in the DOT unlock pattern screen. Or a way to put a different lock cause that icon gets on my nerves. Every time i put the phone in my pocket and accidently push a button in my pocket it automatically calls 911 without me knowing. Im going to end up getting in trouble maybe. Plus its just annoying. I wanna know if anyone knows how to remove it or set a different type of lock or something to just prevent it.
