Boost Mobile chief: Unlimited plan picking off T-Mobile customers

The head of Boost Mobile, Sprint Nextel's prepaid unit, said that Boost's $50 per month unlimited plan has been doing well since it was introduced nearly a month ago. Matt Carter, the unit's president, said that the unlimited plan has not resulted in cannibalization of Sprint customers. Instead, he said postpaid subscribers are migrating from T-Mobile USA over to the Boost plan.
