Not to confuse matters, but Nokia and Siemens have another, unrelated deal in the works. Siemens Communications--the enterprise part of Siemens that's staying (for now) with the parent company--is working with Nokia's enterprise business on a fixed-mobile convergence [1] agreement. The idea is that Nokia's dual-mode E series phones will be able to work with Siemens Hi-Path Mobile Connect Solution to hand off calls as necessary between WiFi networks and the cellular network. The companies were hinting about this broadly at last week's VoiceCon; this week came the official announcement.
