Touch Diamond - Cool things you might not know about

[kennya]

So after reading this forum for a few days, I've read that the Diamond can do some pretty cool things that I didn't even know about. I'll list them here:

- During an incoming call, flip the phone so the screen faces the table, and it will ignore/silence the call
- The center button can be used as a scroll ...zoom in and out in Opera and files
- Voice Command can not only control who to call, but you can say things like "Play Metallica" to play an MP3 file, or "When's my text appointment?" and it'll read it to you.

Can you add to this list?
