Apple has filed a defense with Australia's Federal Court, contesting an argument by the country's Competition and Consumer Commission that the third-gen iPad shouldn't be marketed as 4G in the country. While the tablet does support LTE 4G, it is currently only compatible with LTE networks in Canada and the US. Apple suggests that 3G networks run by Australian carriers Telstra, Optus, and Vodafone are "4G networks in accordance with accepted industry and regulatory use of the descriptor '4G.'
