I don't usually tether, but I did set it up after rooting just for the hell of it. I have Open Garden from the Play Store. I had to set the device as an Optimus S too. Then I had to download a user agent plug-in for my laptop's browser (I was tethering to the laptop &I use Firefox on it). After installing the plug-in for Firefox onto the laptop I had to manually enter the user agent from my phone into the plug - in. A quick Google search on my phone led me to a website that gave me the user agent to put in on the laptop. I think that was all I had to do to get it to work, but it's mobile web, not the regular internet.
