Dear T-Mobile Support,
I am writing you this to inform you that there is an exploit in
your system that allows customers to use your tethering service without
having to pay for the tethering feature.
Users can do this by using an app available for purchase from the Google
Play store which allows a non-rooted phone to enable tethering threw
Wi-Fi or Bluetooth with other devices without paying for an active
tethering feature.
The name of the application that utilizes this exploit is named FoxFi
and is available on Google Play:

I bring this to your attention because as a paying customer of tethering
services, I realize that customers are in fact stealing the service
which creates a negative price increase on legitimate customers who pay
for the service. Not to mention creating numerous network burdens and
profit losses for your company.
If further information is needed you can contact me via the phone number that is listed on this user name.
