Is internet passthrough available for the HTC One on Sprint? And if so, do I need to root or can we do it without rooting? I have a friend that has an HTC One for Sprint and we work in a building where she gets no internet and she wants to use it so I thought internet passthrough would be her solution. Btw, our office computers run Windows XP. If HTC Sync is required, would it run on XP? Or would whatever alternative method run through XP just fine? Thanks!
