Okay, this is very weird. Both my wife and I have iPhone 3GS's. We've both just updated to OS 3.1. Now, my 3GS only shows the following choices for the "Require Passcode" option. Immediately After 1 minute After 5 minutes After 15 minutes However, my wife's shows two more choices. Immediately After 1 minute After 5 minutes After 15 minutes After 1 hour After 4 hours Anyone have any idea what's going on here? I had mine set to 1 hour, but it's forced to be 15 minutes now, and I totally hate it!
