Hey everyone. Kind of new to android. Have played a lot with my Evo with much sucess trying different roms, themes and I'm now at a stand still with things. I'm running ava v9 and want to know if there is a better radio to update to. I've never messed with the radio and honestly, I'm not sure exactly what the radio is for. Is it for 4g or internet or what? Hope this isn't too stupid of a question.
