What is Tethering

Tethering is a way to have Internet access on your PC through your smartphone using it's network connection. Usb and wifi access point tethering is natively supported from Android Froyo ( 2.2 ). Older versions of the Android OS, mostly unofficial roms have this option enabled.

Wifi access point

Since Froyo ( Android 2.2 ), wifi access point ( use 3G ) is accessible by default, without the need to root the phone. Moreover, this method will not discharging battery too fast like USB. See : menu/wireless & networks/Internet tethering/Wifi access point
