I haven't updated yet, because I want to keep the tether functionality. I rarely use it, but when I need it, I need it. I remember a few months ago people were saying you couldn't root the GB update and tethering was axed. It looks like it's rooted now, but are people tethering again? I usually use barnacle, but I'm not married to it. But about once a month I'll need it for ten minutes, and then it's vital. Anyone using a tethering app with the GB update successfully?
