With much fanfare, Verizon Wireless announced a plan to open their network in November 2007 (see this). A podcast I was listening to today lamented that Google's Nexus One has become a GSM-only developer phone (despite the success of the Android platform on CDMA). This caused me to wonder about what happened to device portability on CDMA ... I have seen or read precious little about this project since then.
So was the Nov 2007 announcement a public relation stunt to appease regulators? Was it more difficult to implement device portability on CDMA more difficult than they had imagined? Did consumer interest in portability not materialize?
