I am getting a new iPod Touch soon, and I heard something where you can install VOIP and use it as a phone by installing Skype. I have a couple questions: 1. With Voip, does it give me my own phone number on the touch where people can call me, even while just listening to music or while my touch is on but sitting at a desk or something? 2. How much do minutes cost? 3. I assume the mic and headphones from the new ipod earbuds work with the phone?
