Bluetooth accessories are useful because they provide a liberation from wires and and the devices with which they connect. This controller, however, has rotating handles to help lock in your Series 60 handset for gaming, thus making the Bluetooth feature kind of pointless. You can use it with Windows Mobile, though, so download some mobile first person shooters and go nuts. The controller itself resembles a Playstation controller with no shoulder buttons and a white finish with folding handles for portability. One AAA battery will net you 3.5 hours of gameplay which should be enough, especially considering that you're playing on a cellphone. These are going for $50 and are available now.
