Offender Locator is an iPhone App that lets you use the GPS on your iPhone to find registered sex offenders living near your current location. You can also see if any registered offenders live near any contact in your address book, or manually lookup a specific address.

Should any registered offenders be found, the app displays their photo, and the offense they committed. Currently available in a free "Lite" version, or $0.99 for the full version, Offender Locator is compatible with iPhone and iPod Touch running iPhone OS 2.0 or later. More details available via the developer's website.
