The third forensics book in this batch is iPhone and iOS Forensics (IAIF) by Andrew Hoog and Katie Strzempka. This book is similar to iOS Forensic Analysis: for iPhone, iPad, and iPod touch by Sean Morrissey. Oddly enough, the aspects of Morrissey’s book that were most compelling are weaker in IAIF. I prefer for forensics books to avoid using jailbreak techniques where possible, but it would have been helpful for the authors to be very clear where and why they use such methods.”]
