OP, I've owned my 1020 for 14 months. Just now, I heard a slight whine coming from my camera module - it only occurs during sudden movements, and is very slight/quiet. I've tested it on video, and unfortunately it comes back when recording video and shaking the thing in a particular motion. I'm here in NZ too on Spark, but bought the phone last October - what do you think?
Update: okay now it seems to have gotten worse and is easily repeatable by setting the focus to macro and swinging it back and forth. Thankfully, the Nokia warranties are for 24 months(??!!!), which is quite generous compared to Apple's 12 months. I'll be taking it back to the store to get it fixed :S
