I believe that the Iridium sats are not tumbling, its just the reflective solar panels that happen to shine onto a certain location, I could be wrong but if it was spinning it would have a variable brightness that is unpredictable. I caught a tumbling sat once in an exposure of m42 as seen http://i.imgur.com/S0wJRYS.jpg here, it makes 3 different reflections.
