I plug my phone into the USB port on my computer, Enable USB tethering when it asks, and can never get internet connection working on the PC. It says right on the option that it uses my phones 3g connection to enable internet access. Does not indicate a need to be connected to a wi-fi network or anything. But it never works. Has anyone got their USB tether to work ever? Im not talking about the $30 a month wi-fi tether.
