Super Bluetooth Hack. There are a few reasons why I don’t keep Bluetooth permanently activated on my cell phone, and this type of program is one (battery life is another!). Although this is not strictly speaking a full hack (the first time you use it, the target phone has to grant access) once you’ve got permission you can run riot on the other handset at will (as long as you’re within Bluetooth range of course). Like browse contacts, make calls, read SMS messages or even switch the phone off. It’s a Java application, so it will run on almost every handset on the market. See the video for a demo.

If I was being charitable I could probably spend some time and come up with an innocent and valuable use for this tool, but the sleazy ones pop into my head first for some reason.
