Hi, I have installed the "lock" app. By default it locked my settings tab, it did supply a password for me. Besides settings it also will allow you to lock: browser, network controls, store, calendar, alarm clock, and camera. I did not see a way to assign any other applications such as a journal or office documents. I understand the locking the settings and network settings and the store along with the browser. But the inability to add additional apps really limits its value for me.

Regards,
