said by Body Count:I like the idea of cracking down at the terabyte users. As long as it stops there. I know people who do use 100+ gigs a month just on their phone and do not tether. You start targeting these people and that's where I have the problem.
Based on the faqs, they're targeting people who are bypassing the "pcweb.t-mobile.com" APN used for tethering.
I doubt they'll target heavy smartphone users as I sometimes do 100gigs/month (non-tethering).
