To do this I had to install a tweak called tetherme for my iPhone 4 running 5.0.1 via Cydia. I'm not sure whether you will have to do the same or whether it is already in the software as normal. I don't think tetherme is compatible with the 3GS, but there are others out there that will work for you using USB. Try tetherme, but I'm sure when I installed it, that it said it only worked for the iPhone 4, but they may have been just for wifi, therefore working with yours on USB.
