Apparently I have been unable to find a way to register a wireless account for the iPad with AT&T. It was simple for iPhone but every registration screen I have attempted for the iPad fails. Perhaps you cannot do so since with 3G it is unlimited plan and there is no need for registration but you'd think they could link the accounts with your iphone and home accounts. I was told by International Customer Service that I needed to go online to remove the International plan at http://www.att.com/dataconnectglobal. There is no place to register my iPad phone number. The only options are phone, home and business. Does AT&T not have a wireless account registration for iPad?
