So, I like having the security of requiring a password or pin to unlock my Lumia. The thought of a stranger picking up my phone and immediately having access to all of my contacts, my facebook account, email account, etc. gives me the creeps. I realize that inputting a short pin # to unlock my phone is not a big deal, but I have seen some of my iPhone friends with an app that allows them to use a particular finger swipe to unlock their phone in lieu of a pin #. (An image of this sort of thing is below.) Does anyone know of an equivalent app for WP8?
