Smart Settings from MobiFun Soft installs a 'Start menu' on your home screen. The start menu is fully customizable - you can include all your favorite applications and contacts. Smart Settings can also disable the standard unlock combination for non-touch UI phones (S60 3rd Edition). You can replace it with the most convenient and secure combination for your phone. As a bonus Smart Settings can also set up auto lock period in specific profiles.
