We have assumed that Symbian's days were numbered ever since Nokia announced its intention to go with Windows Phone 7 for its smartphone line, and the end of the road is rapidly approaching in at least one part of the world, according to recent reports.
Chris Weber, head of Nokia's North American operations, told AllThingsD that the company will pull Symbian support in the US and Canada once it begins shipping Windows phone 7 devices.
Weber was quoted as saying that Nokia "will essentially be out of the Symbian business", at least in the US, when the Windows Phone devices launch.
Dropping from the North American market doesn't mean that Symbian is dead in the rest of the world, particularly in emerging markets, but the move sends a pretty clear message and could indicate similar plans for Europe.
That said, Nokia has just unveiled an entry-level Symbian model in Europe, so a complete shutdown of the operating system might not be coming so soon.
