Be warned, this is not for the forensic newbie. You'll want to be comfortable with the command line at the least. More likely you're experienced with computer forensic work in general, or I hope so if you're expecting to go to court! While Jonathan does a great job writing at length about recovering the evidence and of iphone specific discovery, you're going to have to apply general forensics knowledge after that to finish and complete your discovery. This shouldn't be a problem for the audience of the book though.

The book covers recovery for firmware 1.0.2 through the latest release as of this writing, 2.1. Pre-1.0.2 recovery requires either a method that the author does not know about or is perhaps not feasible. In that case the author recommends upgrading the firmware as a last resort. Not a very good solution, but that's not Jonathan's fault. If anyone knows another way, please do shoot him an e-mail and he'll probably add it to the errata.

All in all an excellent book on the subject. Anyone who needs to do some iphone/ipod touch forensics would be remiss not to pick this up. Even if think you can just grab the payloads and do it yourself, there's alot of pitfalls and helpful advice on evidence collection and discovery you'll be missing out on!
