AT&T has been trying to crack down on unauthorized tethering on the iPhone and iPad for a while now. One of the crackdowns that AT&T implemented was the tiered data plan that stopped unlimited data plans that many people, including myself, desire. Another was when AT&T began texting people that they would switch people to tethering plans if they kept using so much tethering data on the iPhone. Telling AT&T that you didn’t know what tethering was a work around for many people, but apparently AT&T will begin forcing people into those plans soon.

Thanks to the grandfather clause, customers should get to keep those unlimited plans until they sign another contract — unless their iPhone happens to be jailbroken and they’re using an application like MyWi…

9to5Mac reported this morning that AT&T is going to start forcibly switching jailbroken hotspot-ers off of their unlimited data plans beginning August 11th. While this won’t affect customers who utilize native tethering, folks who use apps like MyWi might want to pay attention.

“Earlier this year, we began sending letters, emails, and text messages to a small number of smartphone customers who use their devices for teetering but aren’t on our required tethering plan. Our goal here is fairness for all of our customers (this impacts only a small percentage of our smartphone customer base).”
