The full picture of what killed Iridium is written up in great detail in "Eccentric Orbits". I'm only part of the way through the book, but lots of interesting stuff in there so far.

There's an excellent and fascinating book that describes, among many other things, how the satellites were saved from being "de-orbited" (crashed) about 20 years ago. It's called Eccentric Orbits.
