Icahn's New Motorola Message

Motorola's fortunes have faded last year with the declining popularity of its iconic Razr phone. And there have been no new models to take up the sales slack. In fact, the much anticipated Scpl platform recently hit a snag, spoiling any chance of an immediate turnaround at the mobile phone giant.

Concluding his letter, Icahn says he wants to be "an active, constructive Board member and to help guide Motorola through its current difficulties so that it can achieve its full potential."

Motorola shares were unchanged in midday trading Friday.
