sprint-nextel, or playfully "sextel". the future of nextel is not going to be in iDen technology. i've heard it'll be around till 2007ish, and that motorola is going to make a dual mode handset for CDMA and d-amps.i just don't think that it's going to be anything spectacular. how much r&d could possibly go into a condemned technology.anyway, there's alot of time before your iDen doesn't work. but you may benefit from a CDMA phone on sprints network once that becomes available.
