Boost Mobile, Sprint Nextel's prepaid unit, said it was phasing out CDMA-based products, and will instead focus on building up the iDEN network. "Boost Mobile will still operate, support and service its CDMA-related products, but it will no longer promote them," Boost Mobile spokeswoman Tatum Hawkins said. "If customers wish to sign up for CDMA-based services, they may still do so. However, Boost will no longer create new CDMA products and/or services, nor will it add new CDMA phones to its roster of devices." Article
