After we upgraded to iPhone 4, one of our old iPhones was pressed into service as a children's video playback device for our 1.5 year old. That's one of the best things about an iPhone upgrade -- every upgrade comes with a "free" previous-gen iPod touch!
And, well, The iPhone is the ultimate kid-pacification device. With one caveat.
He does well holding it, most of the time, but tends to push the home button or accidentally activate enough touchscreen controls to stop video playback at the least or kick out to the home page.
Is there any way to activate a "locked" or "children" video playback mode on the iPhone, where accidental button presses don't stop video playback?
