Ok so I am still trying to do this, and the edit thing is confusing me where do I found this edit button, can some one post a screen shot of this screen where edit button is .I have a xv6700 Ok nvm. I finally just decided to press the talk button and i found edit. Yes I know your sitting there asking yourself why in the hell did I not think to ever press the talk button, but hey we all have our retard moments just mine occur more often than not...lol
Thanks in advance

On my mogul, I've also got the option for "Voice 13k - IS733". Anyone know the different?

Doing these changes or any others to my phone, should I be worried about changing things back if I need to take my phone in for customer service for any reason?

Anyone know the difference?

When I do this, only my MDN and MSID information is shown... any ideas ?

From what i understand...leaving it on is the best option because if u dont, the voices can actually sound robotic and distorted if u r driving or around loud noises...and could than sound worse. It will only really be better if u r in a very quite environment and not moving...or else it could backfire and go from better to worse.
