Saw on another forum. Have the 1st gen and love it!

* Works on all capacitive touch screens - iPad, iPhone, iPod Touch, HTC HD2, BlackBerry Storm, Gphone and any capacitive touch panel device
* Conveniently designed in pen form; Perfect for carrying around; Comes with Retail Box
* Durable construction; Detachable tether (that is attached to the top of the stylus)
* Perfect for cold days when you don't want to remove your gloves
