So I've been reading several of the threads in regards to AT&T tethering notices going out since they first began in March. There seems to be no apparent rhyme or reason to who is and isn't getting the notices. We've seen it span across various methods of tethering (MyWi, TetherMe, PDAnet), and even in a variety of data usage (as few as 200MB, and more than 7-8GB), one pattern that I haven't seen anyone discuss is geographic location. It's possible that AT&T hasn't rolled out their detection system to the whole country yet, or that they're specifically targeting areas with heavy network use in order to reduce congestion. I for one use between 1.5-2GB every month, and tether with MyWi and haven't gotten a notice yet (although I scaled back my tethering usage quite a bit for about 2-3 weeks after I heard about the initial notices being sent out). I live in Wichita, KS and while we have decent 3G coverage here, AT&T tends to be very slow at expanding 3G coverage outside of the immediate Wichita metro. Clearly I live in a low priority region for AT&T, and I'm wondering if this is the reason that I haven't gotten the notice. I propose that we have people (who tether unauthorized) post their city and whether or not they have received a notice. Maybe we'll see some patterns emerge, or maybe my crackpot theory is just that... crazy. For simplicities sake: Wichita, KS - about 2GB of usage per month, MyWi, no notice.
