Embattled No. 3 mobile phone maker Motorola is expected to announce layoffs and a restructuring of its mobile platform strategy during its third-quarter earnings report tomorrow.

According to today's Wall Street Journal the Schaumberg, Illinois-based company is dumping three of its mobile operating systems to focus on Windows Mobile, Android and P2K OS, its proprietary Linux-based platform. Motorola also has used Qualcomm's BREW, Nokia-owned Symbian and the Symbian-based UIQ.

Motorola is also expected to lay off an undetermined number of employees as part of its mobile division spin-off, scheduled to happen next year. Motorola did not return calls or e-mail inquiries by press time.

The published report didn't surprise industry analysts, who are anticipating disappointing results tomorrow on mobile device revenue and sales.
