Can my HTC Evo 3D be updated without rooting it or having any service? I am running 4.0.3 w/ 3.6 sense, I use WiFi and currently don't have easy access to a pc to root it. The idea of rooting makes me a bit uneasy as I'm worried about doing damage but in the event I do, can I do it without a pc? Is there an easy (ish) way to do any/all updating in my current situation? Thank you for helping
