One Great Shortcut for the Storm is to...
HOLD DOWN THE MENU BUTTON FOR 3 SECONDS.
A Shortcut menu will pop up which will allow you to easily go from one app to another seamlessly.
This will also show you what programs are running.
I cannot stress the importance of closing programs that you are not using. To do this, go into the program that is running, click the menu button, then select close.
Remember to CLOSE your apps when you are done....Pushing the red button does NOT close an app!!
