I tried to get them to let me do it too.. but they won't...
If you go through the motions of sending it in, Make sure you print out a copy of this link:
http://usa.canon.com/cusa/support/co....mc_id=C126149
and include it--Along with your letter indicating that it is a FREE upgrade....
As you might get a $232+ bill for the "Repair"...
I did, twice in an email, and once via snail mail.... I finally, after contacting them twice on it... by phone (Call the repair center directly)...
Get it Free....
I'm waiting for the return of the camera now...
Here's a partial copy of the email they sent:
Dear JAN :
We have received your equipment for evaluation and repair. Based on our initial examination, we will start the necessary repairs at no charge to you. You can expect the repair to be completed and returned back to you within approximately 7 business days* from the date shown above. There is no need to respond to this notice.
Please note that in the unlikely event that any additional internal damage is found due to liquid/water, sand, corrosion, battery leakage or impact (such as dropping the unit), a revised estimate will be sent for your authorization, since these conditions are specifically excluded from warranty coverage.
Thank you for purchasing Canon products and for allowing us this opportunity to serve you.
Best Regards,
Canon Factory Service Center
