AT&T is finally preparing to crack down on iPhone users who take advantage of jailbreak tethering solutions to avoid paying for the feature. 9 to 5 Mac reports that as of August 11, any iPhone user who uses such a solution to tether their phone and has previously received a notice from AT&T regarding their use will automatically be switched from their current plan—including grandfathered unlimited plans—and onto the 2GB/$25 plan, and will have the $20 2GB tethering option added.
Users who stop tethering before the date will apparently be able to keep their current plan. AT&T confirmed similar plans in March of this year, but apparently had yet to act upon them.
