yes but what about associating a phone number with the one on the ipad, because less people know my email than my phone number. or if i associate an email with the one on my phone will it pick it up on my ipad when one sends one to my phone number?
But what about iPod touch users? That's why Apps like Whatsapp fall short on; they used Phone Numbers as screen names but Wifi iPads or iPod touches don't have phone numbers.
