I was wondering if there were any alternatives to the password lock, because it's very easy for people to see what you're typing. i was thinking of a normal slide to unlock, that then takes you to a screenshot of your home screen. you then tap on certain areas in the right order, à la iDiscrete, and it loads to the proper homescreen. anyone who doesn't know the way to unlock would just think the device had frozen, as they would be on an unresponsive homescreen this would be much more subtle and better than the passcode lock. i don't know if something like this exists, but now you know the kind of thing i want, is there anything similar?
