I have the OTA Froyo update...now I have a few question so i can decide what to do next. 1. Can still root my phone with my Froyo 2.2? 2. One of the thing that came with Froyo update is Wifi Hotspot which apparently is not free. I know theres a method of getting it for free. But my question is what is the point or the advantage of tethering? Is there a difference between Wifi Hotspot and tethering? no right? If theres a computer near by why dont you just use the internet on the computer instead of using it on your phone? I read theres wireless tether which is pretty like wifi Hotspot. Sorry for the newbie questions but I just want clearly understand things before I do anything.
