What justification does the author of the book give for installing an agent onto the iPhone
1) is it because of necessity, perhaps a suggestion of recovering deleted data or system info etc not accessible by the user?
or
2) because it is easier to get another device to suck off all the data as it saves time rather than conducting a manual examination where no agent is loaded and the examiner users a video or photographs to demonstrate what is on the phone?

they make a software product called "WOLF" that is designed specifically form Iphone forensics. You have to use a Mac for your analysis machine, but it does not jailbreak the phone.
I have not used this software, but am aware of it as an option.

MacLockPick can be used to acquire the information from an iPhone without the need to jailbreak the suspect's iPhone. It's cross platform and works on both Mac and Windows machines. It's also offers a large number of other abilities such for acquiring forensic data from a suspect machine.
