Sony Ericsson is in the middle of a surprise, major cost-cutting measure that will close some of its key buildings, an internal memo has revealed today. The cellphone designer is notifying workers that it's closing its Research Triangle Park facility in North Carolina as well as offices in Chennai (India), Kista (Sweden) and Miami. As a result, Engadget hears the company will have to drop 2,000 jobs, or more than four times the 450 jobs it dropped in 2008.
