Did you ever wonder where GeoNames webservices are called from? We have analyzed 470M reverse geocoding calls from January 2011 and created some heat maps.
Smartphones make about half of the calls. While Android with 150M reverse geocoding calls is leading ahead of the iPhone with 100M calls, the iPhone covers a larger area.
Comparing Android vs iPhone we have found that Andoid is leading in Northern Europe, the United States and India. The iPhone is extremly popular on the Arabian peninsula and many megacities.

Hello, thought you might like to know the London Android user group are organising a hackathon which will likely attract around 70/90 professional Android developers and attract lots of community attention. We’re looking for APIs to speak at the start of the event and take part with helping developers adopt their services. Please let us know if you are interested or could forward us on to someone who would be.
We’ll be giving tablets to all the attendees to develop upon during the event and awarding tablets to some winners.
The event will be run on Friday 27th till 3pm on Saturday the 28th of May.
