In order to change the notification sound on the GMail app you can do the following:


Open the GMail app and press the menu button (the one to the left of the Home button)
Press Settings and then choose the email address (not general settings)
Touch the word "Inbox sound &amp; vibrate"
Click "Sound"
Then there is a popup for the choice of notification sound you want for your email.
