Japan's DoCoMo to start selling iPhones DoCoMo, Japan' biggest mobile carrier, had long resisted taking on the iPhone, which remains the most popular smartphone in Japan despite the ascendance of Samsung's Galaxy series elsewhere. DoCoMo, a pioneer in mobile Internet and one of the last of the world's large mobile carriers still not offering the iPhone to its 60 million customers, said in a stock exchange statement that it had nothing to announce on the matter. The sources said DoCoMo would continue with its planned winter promotions for handsets made by Sony, Sharp and Fujitsu. Although DoCoMo's negotiations with Apple had been shrouded in secrecy, it was widely believed that strict contractual obligations typically linked to iPhone sales would have conflicted with the Japanese mobile leader's practices. The sources said it was not clear exactly when a DoCoMo iPhone would go on sale.
