First phone running Firefox OS has same specs as N900 have. Specs are not official but are leaked ahead of MWC. Phone which will be running Firefox OS is ZTE Open. Exactly same specs as N900. 256 mb ram, Coretx A5 cpu (N900 has Cortex A8 cpu), Adreno 200 gpu. Can anyone try to port Firefox OS in N900 ? This will run without any problem in N900 i guess.

edit: Processor is running at 1Ghz and there is also another phone running firefox OS. Firefox OS launches at MWC on ZTE Open and Alcatel OT Fire
