The iPhone is a /lot/ more complex than a disk drive, with a bunch more ways to talk to the world. (Also, I don't know if the iPhone has a secure boot ROM. It might, whereupon Apple blew it somewhere else).
This stuff /is/ hard. I sat next to a bunch of folks doing this on a console platform and the techniques and exploits were, in a word, breathtaking. But if you know what you're doing and your scope is limited -- to a smallish device, for instance -- you can make it very hard for someone to crack.
