ATTENTION
Some carriers modify the system software on the phones they distribute to seriously cripple the USB tethering feature from standard Android. This app cannot be used on those devices. Please don't waste your time to add "it doesn't work" comment or put 1-star rating for the app. The Online FAQ has instructions on how to verify if your phone is affected or not.
