Asking BlackBerry PIN to use inside the app

Is there anyway to access the BlackBerry PIN inside my app? I would like to have a way to give certain devices unique access to certain things. If the P开发者_如何学编程IN will not work, is there some other sort of unique identifier that would work and I can access?

DeviceInfo.getDeviceId() in the net.rim.device.api.system package will return the unique Blackberry PIN of the device as an int. However, keep in mind the simulator will return 0x2100000a by default unless you change it to something else.

Have you took a look in the API

DeviceInfo.getDeviceId()
