Awhile back we reported that a "Nokia 800" device showed up on Elbert Perez's Occasional Gamer site under the stats he collects. Speculation at the time suggested this was the model number for the SeaRay. That still may be true, but to make matters a bit more complicated a device called "Nokia SeaRay" has now shown up as well.
What does this mean? Maybe a lot, maybe nothing. At the big end, it could mean there are two devices in testing or being used--one the "800" the other "SeaRay", on the other hand they could be one and the same but for different networks e.g. "Arrive" vs "7 Pro". It's fun to guess, but unfortunatley, that's all the info we have now.
