If you want to report something about your phone over email, a screenshot goes a long way.
To take a screenshot you need to download the Android SDK for your machine. It includes a tool called ddms which is the dalvic debug monitor. Dalvic is the Java runtime powering all the apps on your android phone.
Connect the phone to your machine, run ddms from the terminal and go to Device > Screen Capture (or Ctrl-S) for taking a screenshot.
