Nokia has just revealed that it sold 2 million Lumia Windows Phone devices worldwide during Q1, 2012, and calls the results for its devices and services for the quarter “disappointing,” and states that its “difficult financial performance reflects company in transition.”

Nokia launched its Lumia 900 on April 8th, which is one of the cheapest hi-end smartphones ever, at $100 with a 2-year contract. The 900 runs Windows Phone 7, and at its price point, the 2 million in sales apparently didn’t do much for the Nokia, who initially forecasted breaking even for the quarter, and then downgraded the prediction to coming in at negative 3%. The Lumia 900 was initially touted as the Nokia’s flagship come-back phone, but many units were shipped with a connection glitch, and the company was forced to offer replacement phones or credit, to any devices that were obtained before April 21st. It’s evident that the Lumia 900 might have turned out to be a bit of a lemon.

As for Windows Phone 7, it’s been reported that the OS only makes up only 3% of all smartphones sold by AT&T and T-Mobile in the U.S., but Microsoft has made the platform available in 23 new countries, in attempts to capitalize on its usability in low-end technology. Microsoft isn’t exactly going to give up on its Windows Phone OS, and since Apple and Google aren’t so entrenched in certain developing markets, it’s expansion to a total of 63 emerging regions is integral – stores in Argentina, Indonesia, Malaysia, Peru and the Philippines are promoting the operating system.
