Well I pre ordered my Evo couple weeks ago, and the other night I was talking to my mom about it when I brought up Tethering feature and her eyes lit up. She currently uses a Tracfone (yea I know hahahaha) and is asking about getting added on to my plan, which i don't mind. My parents go camping alot and my mom is kind of addicted to Facebook (Farmville in general), so shes trying to look into mobile internet. I know there's a $29.99 fee for activating the hotspot everymonth, but I'm curious if that she activated it on her Evo, and I also did later in the month, does it bill per phone, or plan? Anyone have an idea what I'm talking about?
