I'm a Nexus user who just got the SG3 on T-mobile. I tried to tether the phone to my tablet and relised it shows t-mobile Hotspot so i stopped. Do they charge if I use this feature on the phone? I dont have the $10 tethering package. Do I have to root this thing or what. I really didn't want to root it because I actually like touchwiz. Yup hard to believe from someone who has own all the Nexus phone. Second question, I've been trying to update the phone tothe latest firmwire but after it downloads the update it reboots and at 25% it shows update fail. Can anyone help, thanks guys......
