A way to get rid of stuck pixels on a Canon 40D

After I bought my new Canon EOS 40D and played around a bit I found out that i have a bright white pixel near the center of the captured image. It is called a stuck pixel, or sometimes dead pixel.
I was not happy about this because i thought it meant that I have to send the brand new camera back for a replacement or repair (with a software remapping process to calculate the average brightness and color value using the surrounding pixels around the stuck one).
I thought I’d take a chance myself and google the issue, and deep in a forum I found something, something interesting: It is possible to do this remapping process from the camera itself! And it is easy, just charge up the batteries and go to the menu and initiate a “Manual Sensor Cleaning” then wait about a half minute then turn off the camera: if you’re lucky the stuck pixel is gone! I’d taken several before and after photos, and the stuck pixel really is no longer there…. the problem was fixed!
So if you have a Canon 40D with a stuck pixel or dead pixel give a try to this solution, maybe it would save you a few days or weeks of being without the camera.
UPDATE: According to my visitorts it seems this method works on Canon EOS 400D / Digital Rebel XTi, Canon EOS 500D, Canon EOS 50D and Canon EOS 5D Mark II too.
