The patent doesn’t specifically cover iPod touches, but rather any mobile electronic device. We should also stress that it’s a patent application that was filed in the first quarter of 2010, and not a granted patent. Even if the patent is granted, however, there is little or no indication, let alone a guarantee, that Apple would bring a product like this to market.
In fact, it could be argues that Apple has no incentive to make it possible for its customers to use the less expensive iPod touch to make phone calls, rather than its own iPhone or, even worse, some other company’s product. If granted, though, the patent could be used to block third party companies from introducing such products.
