Apparently, from the traffic on the Flickr G9 groups, this is a pretty common problem that comes from a poorly sealed lens that sucks in dust every time it extends and retracts. Some have reported sending their cameras to Canon for a cleaning only to have the spots show up a couple months later.
So armed with some small screw driver, pec pads, sensor brush and some eclipse, I gathered up the nerve to tear this sucker apart. - what could go wrong? It's basically useless now anyway right? Anyway here's video evidence it survived the surgery (warning- even though I sped up the video, it's still extremely boring!):
Post operation thoughts? Well, with these small sensors, this really should be done in a clean room the slightest dust is visible - It took two tries to get the image spot free (or at least usable). There are some really small components in there that could easily get lost or broken which may result in a $500 brick but with all that said, would I do it again? - heck yea, I'm not giving Canon another $150 for something that is a result of some poor engineering on their part.

I've got a similar problem with dust, but it's inside my G9 camera lens assembly. I accidentally scratched the outside of the lens trying to suck out the dust, so at this point I would like to replace the lens assembly. Do you know how to do this? I tried to get into the camera from the other side (other side from the screen). There appears to be some kind of metal cage around the lens assembly. I tried to remove the screws holding the cage on, but after removing the screws the cage does not seem to want to budge... Can you help to figure out how to get into the camera to take out the lens assembly?
Thanks - Eric
I have a similar with dust, but my dust is inside the lens assembly. I tried a few tricks to suck the dust out but ended up scratching the outside of the lens. So not I want to remove the entire lens assmebly and replace it with a new one. I have to remove the old lens assembly first. I have tried to access it from the opposite side from the screen and there appears to be a metal cage housing/holding it in. I removed screws in the cage and then tried to pull it off, but it doesn't seem to want to budge. Can you help me to figure out how to get this lens out?

I've never taken the cam down that far but from the pics at this site: http://qman.fotokala.ee/Kaamerad/PowerShotG7/index.html it looks like the camera is built around the lens. It looks like you'd have to disassemble the motor assembly used for zooming before you can get at the elements.
That sounds like it could be complicated - what I'm most worried about is undoing something that can't be redone without special equipment, or taking things apart and not knowing exactlt how to put them back together. The more I disassemble, the more that has to be rebuilt.
