As Nokia starts to roll out its latest slice of Symbian-powered hardware across Europe, the manufacturer has bundled up some upbeat usage statistics for its developers. It's a mixture of global clout, big user numbers and several mobile platforms, with Nokia declaring support from 145 operators, across 52 different markets. Its app hub, Nokia Store, is now available in over 190 countries, while there's now over 100,000 "content items" for its simpler Series 40 handsets, with those devices accounting for 42 percent of the last billion items downloaded. The Nokia Store itself has now served over five billion downloads across all of its mobile OS'. There's also some good news for its most recent addition, Windows Phone, which has already caught up with Nokia's own selection with over 100,000 apps to choose from. Over 20,000 Lumia phones have been offered to developers in tandem with Microsoft's Windows Phone seeding program and, according to the beleaguered phone maker, the ecosystem is now "starting to thrive" -- which is good news, considering Symbian's lingering death sentence. Nokia also took the opportunity to highlight its exclusive third-party app offerings from the likes of CNN, ESPN and Sesame Street -- although the jewels of the Lumia series' app provision arguably remain the in-house likes of Nokia Maps and Mix Radio.
