thanks to give your response. i have already unlocked the usb cradle, but it also display the PC<->MD message

my friend give me her n10, it's nearly new! but when i push the play button, the LCD always display the message"pc--md", and i can't do anything with this device!!! Does anyone know what it means? I have searched all the contents in the user manual, but there is nothing about that. pls give me any info, any guide. thanks a lot in advance.
