Screen Lock application on WM6?

[blablum]

I've upgraded to wm6 and it seems the built-in screen lock application is very buggy, so I'm looking for other options. I'm trying slide2unlock 1.21 but I'm not very happy with it as sometimes it just wont come on. I was just wondering what you guys are using.

This is very important to me as it is the only way to avoid buttcalling when the phone comes on by itself. With wm5 I was using the built-in application with a 0000 password and that did the trick.
