Seems that many think that the Diamond doesn't have a soft reset button and that the only way to reset a hung device is to pop the battery out and put it back in.
However, this isn't the case. The Diamond does indeed have a reset button that you can press with your stylus, it's just in a slightly unusual place. Don't go poking your stylus in the two holes on the bottom of the device, neither of these are the reset button. The square hole is where you attach a lanyard or phone charm and the round one next to the USB connector is the MIC. Don't go forcing your stylus in the MIC hole - we've heard that some people have already damaged their phones because of this.
In actual fact that reset button is located just under the bit where the stylus slides in. If you remove the stylus you'll see a little red button and the word reset. You can in fact press this button if you poke it with the stylus at an angle but it's a little easier to get to if you pop the back cover open a bit.
