Just a thought, I use MyWi but so little that my unlimited plan still stays under 2gb a month so I think I'm under their radar....... for now. It just occurred to me that they could easily tell that I have a JB phone when I download a big podcast. I think, what is the normal limit? I have been JB for so long I take the convenience for granted. I get that it works by tricking the phone into thinking its on wifi but the network still has record of an over the limit 3g download right? My assumption is that ATT first flagged the heavy data users then further checked those users for evidence of tethering but I don't have a lot of knowledge about this, would they need to narrow down the pool or could they just as easy check every phone for signs of mis-use. IE over the limit downloads and MyWi. If they could would it be worth it to them to lose the customers that don't overuse the data? Did anyone get the warning email that uses >2gb a month? Life goes on if I have to add 15.00 to my plan for tethering but it would seriously suck to lose my ability to 3g download. I may use it a few times a year but still... Thoughts?
