I had intermittent mic failure over the week of Thanksgiving this year. The only cause I can think of was a short fall from seat to floor on bus. Another short fall from similar height may have reseated my cable. I'm not sure.
Also, I asked iFixit why they didn't offer them. They said there has to be a demand for them, etc. The guy that responded said he'd add it to their list.
Part was only $5.99 (+ S&H $5) Took 9 calendar days (5 business days) to arrive. It seems in good shape, but I suspect it was removed from another iPhone unit. I haven't installed it yet.

I got mine from Cellular Nationwide Network (Hong Kong).
