IPhone 4s not working (virgin mobile)?

I love singing but I have no vocal training other than random videos on Youtube, (Yeah i know its bad to base your training on that) however i plan to start vocal lessons soon. People tell me i need to work alot on my breathing. Also what type of male voice do you think I'm? Like Tenor or Baritone?
