Questions for J2ME Bluetooth Serial Port connections

When programming J2ME Bluetooth Serial Port connection with a particular UUID, I got a strange thing happened. In Sun Wireless Toolkit 2.5 emulator, testing was very normal. However In Nokia E61, my application was able to connect to not only the device with the particular UUID, but also other devices with different UUIDs. I checked all relevant information on web and books, but no such answer there. So I can't figure it out.

Following the question above, my 2nd question is that after device search, the application gets a list of device addresses. If I am trying to connect to other deive with different UUID and don't know that UUID, how can I find that UUID?

If anyone give me help, thanks in advance.
