A fascinating column on police forensics on iPhones.   Once book is called 'iPhone Forensics".    An article, written up about the iPhone's use in an investigation says:

"There's plenty of information an iPhone hangs onto," Jonathan Zdziarski, author of iPhone Forensics, told FoxNews.com. "For example, the iPhone takes a screen shot every time you hit the home button, including shots of your e-mail with the time stamped on it."

And these pieces of information are also critically useful in an investigation:

It's not difficult to understand law enforcement's enthusiasm for the iPhone. Equipped with GPS, a camera, and a Web browser, it can provide a wealth of data to police trying to track a criminal's movements and actions:

*  Mapping software will store locations you've searched or directions you've received.

*  The auto correcting typing feature of iPhones actually stores words you've typed, which could potentially be accessed months after a message was sent and deleted.

*  Photos taken with the phone can contain information about where, when and with which device the image was captured.

*  Web browser information is also often stored, such as reservations the owner has made or sites they have visited.
