Calling

If you want to make a call using the dialer, you just use the number pad to dial your number and then press the phone icon to the left of your number. The back arrow with the X in it will delete the last digit. On earlier versions of Android, this back arrow was near the top of the screen, next to the number, and the green phone was on the left. I don't know how many times I started deleting numbers instead of pressing the call button. Thankfully, the green Call button and Delete button are more distinct, and are at the bottom of the screen for phones using Android 2.1 and 2.2.

As you're calling, the screen will black out to save energy. If you need to see the screen again, such as when you need to press numbers to navigate a voicemail system, just tap the trackball to wake up the screen.

Red means stop, so if the background turns red, the phone call has ended. You can also hit the red phone button to end the call yourself.
