Calibration is dependant on the lighting in the environment that the screen is in. Someone else's profile is not likely to be particularly helpful for you.

Thats only partially correct. Calibration also corrects colour imbalances and contrast imbalances. I borrowed a friends spyder pro 3 to calibrate my 27", whether the calibration profile it produced would transfer to another iMac of the same make I'm not sure, as it would depend how much variance there is in the hardwares default output.
To be honest though the iMac's original calibration wasn't actually that far off perfect anyway. While some of my previous monitors have been way off.
