Icahn considering Yahoo/Microsoft move?

Billionaire investor Carl Icahn, who has recently campaigned successfully for changes to Motorola's management, is now reported to be turning his attention to the failed Yahoo/Microsoft merger. He's apparently bought around 50 million Yahoo! shares and could be planning to replace the company's board of directors, according to the Wall Street Journal. Any merger between Microsoft and Yahoo! would have a dramatic effect on the mobile industry, as we reported in our podcast in early February.
