[FIX] How to turn off keypad sound on the i580

The i580 has been called "loud and obnoxious" by some customers, but it doesn't need to be that way.

Goto:

>Settings
>Phone Calls
>DTMF (set to "never")

The phone will now not make any tones when you press the keys. This is particularly helpful in not making the person on the other end of the line listen to you press keys when you're digging through your menu.
