Excellent guide to not only useful tools to analyze and recover data from mobile devices, iOS, Android, and MS are all covered. While I felt restricted as the author used Mac OS for most of the operations for the iOS devices, some windows applications that are open source would be nice to have. If this is for a professional company then the $1,500 price tag for one of the software options are not a major concern.
All in all I give this book 5 starts because it did have a lot of solid information despite the lack luster for lower cost software solutions. If you're looking to get into data recovery for mobile platforms or do the forensic work, do yourself a favor and pick up a copy of this book already.
