Root [International] Controlling When Screen Locks


I've got my S3 set up with Activsync on my SBS 2008 / Exchange 2007 network. Group Policy for the mobile is lock at 1 hour of inactivity. I note there is only a max of 30 minutes on the lock screen app. I could live with 30 minutes but the screen locks automatically when I end a cell call on the machine. I do not want the screen to lock unless there has been 1 hour of inactivity or I manually lock it. Since this is a quad core computer, I should be able to program it to work the way I do.

Anyone have a solution for this? I've been googling for a couple of months, on and off, trying to find a solution, no luck so far.

Any help appreciated,
