Regardless of all the iPhone 4 recall madness going on, there seems to be one feature that still has some users pleased: FaceTime. According to Boy Genius Report, it's headed for the iPad and iPod touch. Wait, how?
Obviously, both the iPad and iPod touch lack built-in cameras, and neither has a phone number attached to them. However, there have been plenty of rumors in the last six months about the iPod touch getting a digital camera, and a new iPod touch this fall seems likely to us.
But as for how to actually log on and make phone calls, BGR says all you need is an Apple ID, which will in turn register your device for FaceTime and use your e-mail address for phone calls. The push notification system will prove even more useful now as that will be how users are alerted to incoming calls. Looks like you'll need at least iPhone OS 4.1 beta installed on your device as well.
As for the camera issue, it is still a gray area, but you could remedy this with a third-party digital camera attachment for now. It just won't be easy and simple to tote everything around.
