What Bluejacking software for phones is there which doesn't require acknowledgment?

Where the phone your hacking doesn't need to accept the bluetooth connection. This software was featured in 'The Real Hustle' but they, obviously, don't tell you what software it is! I have BT Info already.

after this questions gets reported you should ask again and choose words more carefully and legally. lol.

But if its still here later I'll help you out.
