In Windows Phone 8.1, I get the Phone Unique Id like this :

private static string GetDeviceID()
{
HardwareToken token = HardwareIdentification.GetPackageSpecificToken(null);
IBuffer hardwareId = token.Id;

HashAlgorithmProvider hasher = HashAlgorithmProvider.OpenAlgorithm("MD5");
IBuffer hashed = hasher.HashData(hardwareId);

string hashedString = CryptographicBuffer.EncodeToHexString(hashed);
return hashedString;
}

I don't know if this code compile in WP 8.0 but maybe it can help you...

Always used the same since WP7:
var value = (byte[])DeviceExtendedProperties.GetValue("DeviceUniqueId");
