Operator partners in the effort include Deutsche Telekom, Etisalat, Smart, Sprint, Telecom Italia, Telefónica, and Telenor. The first devices featuring Firefox OS will be manufactured by TCL Communication Technology (Alcatel) and ZTE using processors from Qualcomm, Mozilla says.
Launching in 2013
"Due to the optimization of the platform for entry-level smartphones and the removal of unnecessary middleware layers, mobile operators will have the ability to offer richer experiences at a range of price points including at the low end of the smartphone price range, helping to drive adoption across developing markets," Mozilla explains.
