Is August 11 the date when AT&T finally starts forcibly switching Jailbreak users who tether unofficially to limited, tiered plans? We knew AT&T was warning users tethering unofficially with apps like MyWi, and that they were threatening to take away their unlimited plans, but when they would start the process has always been a question.

The August 11 date comes from a 9to5Mac reader.

I was just informed that as of Thursday August 11th 2011, if you use MyWi or any tethering on the phone or using the phone as a modem, AT&T will automatically change ur unlimited plan to a 2Gb tethering plan for 45 dollars without the customers consent. This is for those who received emails or texts about the use of tethering without an AT&T tethering plan.

(We assume that the data plan actually being referred to in the quote above is the $45 DataPro 4GB plan which includes tethering.)

AT&T has confirmed that they will be forcibly switching users to the tiered plans, but not the date. Β Has anyone else been given a date by AT&T?
