When my WP7 phone connects to my EAS server I can see among other things it's Device ID (B5B0EA77FE982C6EB38584985E98F221). This ID does not match with anything I can get from the device via API.
Using DeviceExtendedProperties.TryGetValue("DeviceUniqueId", out uniqueId) gives me something totally different.

Does anyone know if there is possibility to get the same ID also from some API call?
