Sure, if I hit the home button and lock the phone before I put it into my pocket it wont run an app, but then I have to enter my password when I take it out. My password is very secure and my fingers are not very keyboard friendly, so I don't like entering my password unless absolutely necessary. Yet, I do want to protect the information on my phone and there are times when I want to lock it with the home button whether it is in my pocket or not. I guess what I'm looking for is some kind of screen blanker app that would un-blank the screen with a two or three tap combination.
