Sony Ericsson today surprised the industry by turning a small profit for its first quarter of 2010. The cellphone designer swung from a $226 million loss as recently as this fall to a $28.4 million surplus in the winter. Some of the recovery came through job cuts but was also helped by a major shift towards smartphones, which included the first full uninterrupted quarter of sales for the Satio but also the late shipping of the Vivaz and its most important phone, the Android-based XPERIA X10.
