Note: TetherMe (native tethering on jailbroken iPhones) sends all tethered data through the same APN as mobile data by default so users won't fall foul of the APN detection method mentioned here.
Of course that wouldn't stop AT&T & Co sniffing browser strings of high data users, but that's a more complicated system to implement.

Or just assume that high data users are all tethering.
