How, where, i've been trying to do this.
I found a website from some fan that had clipped the tone to mp3. Here's the link that I was able to copy and send to my phone. I just pasted it to e-mail and sent it to my phone. When I hit the "go to" on my browser message, it downloaded the tone and stored to memory. Pretty cool.
