EA28 Sleep vs lock

[nuker2guy]

My dad's unrooted fascinate (yes we have the same phone and he won't root) got the EA28 update. He uses the password lock, as well as the puzzle. He said before the update, the password lock would only go on when the phone first booted up, and then the puzzle lock would be used if it ever went to sleep or he locked it. But after the update, if the phone sleeps by itself, the password lock comes on, and the puzzle lock only comes on if he locks it himself. Any help for this?
Thanks

I have an unrooted Fascinate. I can't stand the password unlock. I get around this by hitting the emergency call button, then hitting the 'return' key (the arrow key at the base of the phone). This immediately unlocks the phone without entering any password, and no puzzle piece to deal with, either.
