Screen Lock vs. Phone Lock

[Malm]

Hi All,

Just got my Optimus one a couple of days ago. The annoyance right now is that every time the screen shuts off, my phone locks (password protected).

I would prefer that the screen lock and phone lock were separate somehow.

Ideally the screen lock would be a simple slide bar and then when I want to password lock the phone there would be another button (best even the power/lock button) that I could use.

This way I don't have to put a password in every time the screen shuts off but when I want to password lock the phone all I have to do is press a button.

Is there a way to get the phone to do this? Perhaps I need to download a particular screen lock app?

Thanks!
