Apple iPhone 3G
Password protected icons/apps (thoughts?)
For example, being able to password protect an app or icon like your notes, calendar, mail, photos, txt messages... nothing major, just to be able to apply a 4 digit code like the unlocking of the phone.
This is very useful when people want to "check out your phone". Everyone is obsessed with the iPhone and wants to play with it, but after having it for several months, there is a lot of personal/private information on mine that I don't want everyone to access with a touch of the button.
Does such an app exist? Am I alone with this?
