Japan's largest cellphone carrier, NTT DoCoMo, has not "given up" hope of selling the iPhone, according to CEO Ryuji Yamada. Yamada explains that Apple and DoCoMo are still in talks, but that there are several concerns, such as Apple's insistence on high volume commitments. The CEO also worries about the risk of the iPhone becoming a "mass majority" of DoCoMo products, and the closed nature of iOS blocking the carrier from pre-installing otherwise commonplace DoCoMo apps, such as its e-wallet system or custom i-mode email.
