I happen to love android and own the droid x however having said that 4g is in limited availability right now by ur next upgrade as someone else said will probably available to everything from windows 7 to android to iPhone. I read a lot about new tech items and have not heard very good things about the thunderbolt a lot of bugs once they correct should be an awesome phone. I own both the x and my son has an iPhone I can tell u I enjoy mine more the bigger screen for starters and mine is rooted so that opens it to tons of possibilities but its not always the easiest to use compared to iPhone it's all in what ur used to and what ur looking for I personally love my x but also enjoy os thru my iPad and touch best of both worlds really
