I don't get it. How do you fingerprint iPhones, which are some of the most standard devices on the planet? With Android I can think of atleast 20 parameters that will have unique enough combinations to identify specific devices fairly accurately, but iPhones are vastly less "unique" in this sense.

Your IP, which gives your ISP, Location. Your iPhone Model, iOS Version, iOS Locale. Some iOS features which you may have turned on or off. Along with Apps installed, could easily reduce down a low single digit percentage.

33 bits. That's how many bits of information it takes to identify you out of anyone on the planet, more or less. If your hometown contains about 100,000, for instance, knowing it would count as about 16 bits worth of info toward that 33 bits.
