This news is for those who are using jailbreak iPhones, AT&T decided to remove "unlimited plans" for those who jailbreak iPhones to tether or hotspot off of AT&T's unlimited data plans. Here's a quote from a user who received the AT&T's notification:
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.
An AT&T spokesperson responded with following statement:
Earlier this year, we began sending letters, emails, and text messages to a small number of smartphone customers who use their devices for tethering but aren't on our required tethering plan. Our goal here is fairness for all of our customers. (This impacts a only small percentage of our smartphone customer base.)
The letters outline three choices:
- Stop tethering and keep their current plan (including grandfathered unlimited plan)
- Proactively call AT&T or visit our stores and move to the required tethering plan
- Do nothing and we'll go ahead and add the tethering plan on their behalf -- after the dated noted in their customer notification
