I have recently purchased an iPhone 3G. I have a Windows Vista PC and I have no idea how to get custom message alert tones for SMS and E-Mail. I want to use the songs on my harddrive. My iPhone 3G isn't jailbroken or unlocked and I would really like step-by-step directions on how to do this without resorting to that, but I will take any answer. It Would Be Greatly Appreciated! Thanks!
