About a week ago, I found an app called iCaughtU under the "Updates" section of Cydia. A long story made short: this is the newest reason people have to jailbreak their 4th and 5th generation iDevices. iCaughtU is a tweak by developer Itaysoft. The best way to describe it is through his own words: "iCaughtU allows you to take a picture with the front camera (if available) when the lock password is entered wrong and sends it to the user [via email] with more information like Location and a map." The best part? It's free. The tweak catches up on the slack that Apple's own Find My iPhone app left behind. While Apple's app can tell you the approximate location of your lost device, it isn't pin point accurate. If you lost in a public setting, the odds that you'll be able to tell which person picked it up are second to none. iCaughtU, on the other hand, gives you firm evidence and reference to the person that found your device, especially for iPods, which will always show up as being located at the WiFi transmitter's location. Make sure to download it if you haven't already!
