Google introduced Wi-Fi tethering in Android back in 2010, when it announced Android 2.2 FroYo. However, carriers in the United States did not want people to enjoy tethering for free, and blocked tethering options on all the phones they sold.
To enable tethering on their phone, users would need to subscribe to a costly tethering plan that barely made sense. Nowadays, most of the phones come with the tethering option but as soon as a user enables tethering, your carrier will throttle the 3G/LTE speed, making the connection useless.
The AT&T One X is no different to this rule. However, a new tool from developer t0mmy will allow users to enjoy tethering on their phone without subscribing to any tethering plan.
To use this mod, a user must have root access on his phone with the Android SDK installed. The tool in itself is very simple to use. Connect your phone to the PC with USB Debugging mode enabled. Download this file and extract it on your desktop. Run the “tether.bat” file and simply follow the on-screen instructions.
Credits to t0mmy for the mod!
