If you’re tired of the slide-to-unlock message appearing on every one of your iPhones since 2007, developer To Van Tinh has a solution. His Private Folder app has just gone free, and you can grab it to add “connect-the-dots” unlocking to your iDevice.
My Private Folder is a security app which creates a specialized unlock screen that only you’ll know how to unlock. Simply create a pattern and keep it to yourself.
“When someone messes with your phone they will think that it is locked and only you will be able to know how to unlock it as easily as it ever was,” says the developer.
Requiring only iOS 4, My Private Folder works with iPhone 3GS, iPhone 4, iPhone 4S, iPhone 5, iPod touch (3rd generation), iPod touch (4th generation), iPod touch (5th generation) and iPad. The app isn’t yet optimized for iPhone 5, though it should work.
