The book achieves very well its goal to be a good hands-on guide for both forensic professionals and people interested in data recovery from mobile devices. In fact there are specific sections where it explains how to conduct a forensic analysis and the forensic tools that are available for this purpose, while the rest of the book has parts that are useful for everyone. The book is up to date with the mobile devices that you can find on the market today and explains how to handle them, covering the four most widespread operating systems on the mobile market: iOS, Android, Windows Phone and BlackBerry OS. For each of this systems, there is an in depth explanation of the internals of the operating system, focusing on security related aspects and on how data is stored on the device. This theory session is followed by a practical part, where the author explains common techniques to take control on the device and acquire data from it, starting with standard tools and introducing more specific tools, leaving forensic tools at the end. This scheme lets the reader familiarize with the device and commonly available tools, helping him to better understand how the device works and how to handle it without sophisticated tools that simplify the work. Overall, I think this is a good book to read if you are looking to learn how to conduct a forensic analysis of mobile devices and the related techniques or just want to learn how mobile devices work and how to recover data from them.
