AT&T Busting Unauthorized Tethering

“Because MyWi, the most popular tethering alternative for jailbreakers, uses the same APN as the standard tethering system for iOS, AT&T can see a jailbroken iPhone’s tethering activity very easily”

(Via How AT&T Recognizes Unauthorized Tethering from Jailbroken iPhones.)

 

I’m guessing it wont be long until we see an update to MyWi that will change the APN. And they can probably just start working on some sort of encryption to hide the packets in the normal flow of bits.
