(Telecompaper) It is just a matter of time before Japanese mobile operator NTT DoCoMo starts selling iPhones, CFO Kazuto Tsubouchi told SankeiBiz. This marks a change since 8 August, when he told Bloomberg that DoCoMo could consider changing its position vis--vis Apple smartphones if it can limit iPhone sales to under 30 percent of the total.The operator is paring the number of models by up to half as it focuses on Sony and Samsung phone promotions, he told the US business news outlet.
