In January, Google started allowing people to port their already-existing phone numbers to Google Voice. That means that whatever your regular cell phone number was, you can now have it work with Google Voice directly rather than having to get a "new" number which points to your already-existing number. Has anyone done this with the iPhone? What has your experience been? Supposedly it cancels your phone service but you can re-start the phone service the next day without having to pay an early termination fee... or not? I don't know. I just read about this and would like to know what your experiences have been. Thanks!
