I am getting my iPhone today. I now need to know what are the must haves and must do's when i get it. I hate Apple earphone, i like the ones that go right in your ear, I would like one with a mic. I am thinking V-moda, shure with mic adapter or current sonys with monster mic adapter. Should I change any settings or do anything during setup? do i need a case? I dont want one, looks better without, but will put one on if it may get scratched.
