FoxFi is the best free solution I have found so far for free Wifi tethering. FoxFi like Wireless Teather turns your Android phone into free WiFi hotspot but unlike other apps it doesn’t require root access. There is also a Bluetooth sharing mode.
Currently WiFi mode currently works on most Samsung, Motorola, LG, and HTC phones with Android 4.0. Unfortunately the WiFi mode will not work with some older phones and worst of all those with Jelly Bean installed.
