The phone will be able to download songs through Apple’s iTune Music Store, and the two companies expect to release a product early this year that will allow you to download music over wireless networks.
It is only rumors and speculations that this alliance of Apple and Softbank Corp will give birth to the iPhone, but it is a possibility.
Apple doesn’t have much choice but to start innovating in the area of digital music, as cell phones get more and more multimedia capabilities. See Is the reign of the iPod coming to an end? for my take on the subject.
