Have you ever wished you could set different ringtones for different types of e-mail the way you can for phone numbers? You can, with the latest version of Gmail (2.3.5), now available in the Android Market. With it, you can set distinct ringtones for each Gmail label you use. Here's how:

Before starting, make sure you have at least one Gmail label created and a filter that uses that label.

Step 1: Open your Gmail app and press the Menu Key, More, then Settings.
