This hack is yet another example of why jailbreaking your iPhone 4 is oh so sweet. RecognizeMe is a little tweak available for jailbroken iPhone 4s that uses the front FaceTime camera to scan your face and unlock your smartphone. Yeah, facial recognition tech on the iPhone!
Firing it up from the main lock screen, a red scanner-like bar will give your face the once-over and determine whether your face matches the one you originally set as the unlock. Why would you want this? Well, your face, like your fingerprints is a much stronger "password" than any string of numbers or letters.
There's also a bunch of setting thresholds you can fiddle with to ensure that similar lookalikes or twins can't trick RecognizeMe into thinking it's you. The tweak is kinda cool and it apparently locks out shady characters like Charlie Sheen, which is fantastic!
RecognizeMe is developed by Apocolipse and costs $7. Now, if only Apple would let something like this hit the real App Store, then the iPhone would really be in business.
