The new features of Service Pack 1 provide functionality and tools that help streamline the manufacturing process and ease the burdens often associated with the deployment of updates to devices in the field.

With SP1, developers and device-makers will gain the ability to help prevent unsigned firmware or application code from being installed on a device.
