My phone is Sony Ericsson J10 aka Elm, i need a software (java apps with .jar extension) to hack someones bluetooth which is turned on, actually in a party or celebration at least you can find a active bluetooth, so which software can do it without people's authorization.

I know its bad idea but i won't illegally use it anymore just want to know, promise.

I mean something like NEC N880's control target system.
