According to a report seen on CNBC, Sprint is talking to private investors about selling off its iDEN network, which would allow the carrier to concentrate on its CDMA and forthcoming Wimax networks. NII Holdings, which runs a network in Latin America, and an unnamed group of private investors were among two parties cited as potential buyers of the iDEN network. Sprint purchased the Nextel iDEN network in 2005, and has faced difficulties merging its services with its CDMA network. Sources cited by CNBC said any sale would not happen immediately. Sprint did not officially comment on the matter, and just yesterday canceled a planned $3 billion convertible-preferred-stock sale that it was going to use to pay down debt.
