Does anyone know anything about the plans that Sprint has to merge the actual network? I'm a little confused cuz they have said that they will introduce a dual-mode phone which i have heard will come out by the end of this year or the beginning of next. But their FAQs say that they will employ the Nextel Nationwide Network til at least 2010. Does this mean that they will begin to replace towers and shut down the iDEN network? Just want some info!
