Noob here when it comes to rooting...had the OG Droid for 2 years stock & now have the TBolt stock since it came out. Been very happy with stock Bolt but am thinking I'd like the free wifi hotspot available with root. My noob question is once you root do you have to add a certain ROM for the free wifi hotspot to work or will it work once rooted?? Any info would be great, thanks!
