MyWi is a $20 jailbreak app that lets you tether your iPhone 3G data plan with any other device you have.
A lot of people jailbreak their iPhones just to enable this feature. The $20 MyWi app for tethering is way cheaper compared to AT&T’s tethering data plan which costs more than $20 per month.
AT&T customers who were using some form of unauthorized tethering started receieving a text message this morning stating this.
AT&T Free Msg: Did you know tethering your Smartphone to a computer requires a tethering plan? Pls call 888-860-6789 for details or visit att.com/dataplans.
Following the SMS, AT&T is also sending out this email which basically says that if you want to take advantage of tethering enroll in one of our tethering data plans or we will do it for you. (see after the break).
The email goes on to say that if you don’t contact AT&T by March 27, 2011, they will automatically be enrolled in DataPro 4GB plan that costs $45 per month!
It is unclear how AT&T is figuring out who exactly is using the tethering feature without authorization. One hint could be their data usage over the past months.
Let us know in the comments if you have received an email from AT&T. Also, mention how much data in GBs do you use on average each month.
Dear [Customer],
We’ve noticed your service plan may need updating.
Many AT&T customers use their smartphones as a broadband connection for other devices, like laptops, netbooks or other smartphones– a practice commonly known as tethering. Tethering can be an efficient way for our customers to enjoy the benefits of AT&T’s mobile broadband network and use more than one device to stay in touch with important people and information. To take advantage of this feature, we require that in addition to a data plan, you also have a tethering plan.
Our records show that you use this capability, but are not subscribed to our tethering plan.
If you would like to continue tethering, please log into
your account online at Cell Phones and Cell Phone Plans – Wireless from AT&T, or call us
at 1-888-860-6789 Monday – Friday, 7 a.m. – 9 p.m. CST
or Saturday, 8 a.m. – 7 p.m. CST, by March 27, 2011
