I bought mine 2 1/2 yrs ago too. Found this solution on this site and tried it. It worked perfectly.
Turn to TV mode, set the exposure to 15 seconds by pushing the little "arrow dial" until you have 15"
Push the button to take the picture.
Wait 7 seconds from when you push the button, then turn over and open the battery door while it is "taking the picture."
Close the battery door and turn back on. 
I did this three times and the last time, it worked and the iris became unstuck.
Then I took a million pictures to get the iris moving.
Good luck!

I have the same problem with my Canon S21S, and I was blown-off by Canon "Support" a long time ago. They won't fix them even though it is the same problem as with the S11S because they're too cheap to spend the money.
So my solution is simple: DON'T BUY ANYTHING MADE BY CANON! EVER!

Your camera has the know issue of Stuck shutter, whichhappens after some time (weeks or months) thata camera is notused.

Unfortunately the repair of it requires a complete disassembly of the camera, including the lens, fix it, and then put back together everything.

Definitely requires th skills, tools and experience to do it, so it's recommended that a professional camera repair center is performing this type of repair.

If you look for a reliable and low cost repair service for it, you can look in ebay for such repair services.

Example, look for seller ID Great_items_2004 or with the keywords "Shutter black S2".

Best regards,

A stuck shutter is another common failure mode for digital cameras. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure. The camera may take black pictures (for shutter stuck closed), or the pictures may be very bright and overexposed, especially when taken outdoors (for shutter stuck open).
To confirm a stuck shutter, put the camera in any mode other than "Auto", and turn the flash OFF (you don't want to blind yourself for the next step). Next look down the lens and take a picture. You should see a tiny flicker in the center of the lens as the shutter opens and closes. If no movement is seen, then you likely have a stuck shutter. If so, please see this link for further info and a simple fix that may help:
