Yes there will be only one device. And that will be the commercial device. Developer device does not count as it is not sold. Makes sense ? Oh and as you would know currently there are absolutely no plans for another one after this commercial device. It would need a massive amount of consumer interest to change that decision. But i think this much is obvious.
Please, stop. Don't use this useless rethoric. A communications device, to be used outside it's own development enviroment, needs to be FCC approved is US. Simple like that. If Nokia plans to give ONE phone to an american, it needs to be FCC certified.
