So since AT&T announced today that they will be kicking people off their unlimited data plans for unauthorized tethering I have a question. I have unlimited data, I primarily use my iPhone 4 but I also sometimes like to use my Nexus One. All the articles talk about "mywi" users with jailbroken iphones, since it is unauthorized. But since tethering is built in to the Nexus One and is independent of the carrier, if I tether with it will AT&T force me to a tethering data plan? How can they tell if you are tethering or not? I don't want to lose unlimited data but I'd like to keep tethering with my Nexus One, I just wasn't sure if it was an issue since all the online articles talk about iPhone users.
