I've seen a lot of scattered comments about this subject, but it all seems inconsistent. I would absolutely love to have my phone be a wireless hotspot for my computer. However, I'd like to do this without being charged from sprint. Now I know this is obviously something sprint wouldn't want their customers to do so I have two main questions: 1) Do you absolutely have to root your phone for it to be able to act as a hotspot for free? 2) If so, what would be the negative effects of rooting your phone. I'm assuming it would void warranty. Anything else? edit: 3) Would there be any way for sprint to tell that you are using it as a hotspot without paying?
