Nokia has announced that it has acquired Dopplr, a privately-held mobile service provider for international travelers.

Dopplr - described as a "social atlas" - has a team of just seven people with offices in London and Helsinki. Dopplr is "thrilled" at the news.

In a statement Nokia says: "The Dopplr team brings to Nokia's Services unit unique know-how in creating internet-based communities and showing their journeys, experiences and tastes collectively on the web".

The acquisition will not affect the current Dopplr service, available at, or where it is available via other platforms such as Flickr and Twitter as well as Nokia rival Apple's iPhone as an app.
