I recently bought and iPod Touch 3rd generation, and noticed one of its key features was the bluetooth setting on it. I was thinking to buy a bluetooth headset and then getting an app to call people from my ipod. I have been looking at the other questions that have been answered about this topic, but i guess it just wasn't specific enough for me. So is there any app that is out there that doesn't require jail breaking and is free, unlike Skype where u have to pay? Please explain in detail!
