I don’t normally use my blog for such purposes, but if you’re reading this and have a broken iPhone, and are willing to sell it for a moderate sum, then I am interested in hearing from you.
My plans definitely involve breaking it much further than whatever state it is in at this moment. The first thing I need to do is document all of the parts in use, and figure out a way to get at whatever debug/diagnostic interface(s) exist (there’s even a debug port mentioned in the device filesystem listings when you login to a modified iPhone system). It’s known that the phone/radio modem runs as a separate subsystem (and communicates over serial – look at the crash logs), and so it’s feasible for other software to communicate with said hardware, and have real phone functionality.
