Hello, I am new to the IPod Touch world, I just bought a 2g 16gb Ipod touch four days ago. I have been doing research, however I have not jailbroken my device. I also know there are non jailbreaken apps that I may use to call others in wifi zones. Being phoneless, I immediately jumped on this opportunity. If someone could just give me the basics, such as what app to use, what microphone I will need, etc, you would be of much assistance to me. Also, may I simply plug in a regular microphone and put in my apple ear phones or do I need a specific headset? If so are there are links to where I may buy a head set from? Thanks, Barkwood.
