hey guys just got my Droid X and while playing with it yesterday I was able to tether with my Macbook 10.5.8 without any problems (it was actually really easy to do no root needed, no app required). So not sure if this is new to anyone but hey I'm not paying $20 extra every month and still able to tether for free without data cap. Let me know if you guys are not able to do this, I'll try to do a video over the weekend. Droiiiiid
