Nokia has noted Microsoft's announcement of the new Windows Phone 7 (aka Mango) with word that the software being demonstrated today will be the one we'll see on the first Nokia with Windows Phone device. That's singular, not plural, indicating that Nokia will likely start off with one phone and work its way up. It also slightly contracts the roadmap for the first handset born from the Microkia partnership, though Nokia's statement makes sure not to make any promises about when said device will show up. Finally, we find the "Nokia with Windows Phone" phrasing somewhat peculiar, don't be surprised if you see it turn into a branding strategy for Nokia's smartphones going forward. Here's the relevant statement, straight out of Finland:

"Today Microsoft has announced the key new ingredients of the latest 'Mango' release of the Windows Phone operating system. This is the software that will be used on the first Nokia with Windows Phone device, and so should be of keen interest to Nokia-watchers everywhere."

Update: Microsoft just concluded its keynote with word that it already has Nokia phones running Mango in its labs. And none have leaked out yet, amazing!

Update 2: We were just contacted by a Nokia representative indicating that there was a mistake in the original announcement the company distributed. It wasn't supposed to read device, it was supposed to be devices. More than one!

Update 3: Nokia's Executive VP of Smart Devices, Jo Harlow, has told Forbes that the forthcoming "small portfolio" of phones -- which are currently on target for a 2011 release -- won't look like the renderings we've seen before. Not only that, we may see a CDMA Nokia handset at some point, as the company is "working in that direction."
