I wanted to take some screenshots from my Nokia E71 and wondered how do I do it ? So searched around google and found this really light application for the phone. Its called Screenshot by Antony Pranata.
But as the Nokia E71 does not have camera key , which is default in the screenshot app to capture a screen, So you can go into settings to change the default key. I have assigned it as the backspace key and took the above screenshot. As the call was in progress when I took the screenshot hence a green icon appears in the top right corner of the above image.
Hope this helps
