Microsoft has poached Symbian executive VP Juha Christensen to take charge of sales and marketing for its wireless business. Christensen will report to Paul Gross, who's currently in charge of the wireless business, within Paul Muglia's group. The organisation of Microsoft's wireless operations however remains somewhat opaque to the outside world - it's pretty clear that the company is putting a lot of resources into ramping them up, but who's doing what seems to change radically as the weeks go by. With a bit of luck, Steve Ballmer (or indeed Judge Jackson) will reinvent the company again, and issue some up to date orgcharts. Christensen is a serious catch for Microsoft, having been one of the senior VPs at Symbian, in charge of marketing and sales, and a high-profile public face. ®
