Its not that great really bluejacking is ok on the mobile phone level on PDAs you want to bluesnarf lol now that is alot of fun. Sniper is ok but i dont like it much its too graphical theres a program called btcrawler which can bluejack and if you really want to edit your registry you can get a bluesnarf option aswell.
