Sony Ericsson Mobile Communications sales and profit dropped in the first quarter of 2011. The company shipped 8.1 million phones during the quarter, a 23 percent decrease year-on-year. The release of the Xperia Arc and the game-centric Play smartphones late in the quarter meant it failed to make up ground with shipments of high-end phones. The average selling price per phone was 141, a 5 percent increase year on-year and an improvement on the fourth-quarter average of 136 per phone.”]
