Separate ringtones SMS and email for EVO

Working as a SysAdmin you can get notified of emails which are not critical and SMS messages which for me are critical alerts of a problem I need to look into. For this reason, I changed my SMS ringtone from the default.

Select “Messages” -> “Menu” -> “Settings” and select the ringtone you would like for messages.

To change the email notification ringtone, from the home page, select Menu and settings and select the ringtone you would like.
