Andrew Hoog, Chief Investigative Officer at Via Forensics, put together a good summation of the available forensics techniques for recovering data from the iPhone. This paper is a few months old, so it doesn’t cover my latest USB method (which is much faster and easier), but he does cite my original method from the book, along with some other useful methods. Depending on what kind of information you want to get, there are different techniques you can use. Andrew has informed me this paper will be updated shortly so keep an eye out for a new edition.
