I am new to Android phone (coming from Iphone 4s). I bought a used Metro S4 and got the unlock code from Metro - now using the ATT sim successfully. It is running 4.3 stock rom. Now I would like to root it. I have seen various methods (honestly look a daunting task to me) but I have jailbroken iphones before. Can somebody let me know if I can root the phone and still use ATT Sim? Any simple installer than I can run - simple one download and then root it?. Somehow when I pair this phone to my car, I can listen to audio but can see the tracks that come from internet radio - any idea on it Thanks you - you folks are doing an awesome job helping out folks like me.
