Microsoft held its developer preview of the Windows Phone 8 operating system on Wednesday, and revealed that it is shifting the platform to share core kernel features with Windows 8 for better integration.
At the rollout event in San Francisco, corporate vice president of the Windows Phone program Joe Belfiore said that Microsoft's Phone OS had been built around the Windows CE core, but that this wasn't good enough anymore, so the new mobile platform had been rewritten around Windows 8.
