My iPhone keeps losing my place in my Audiobook.

This is fairly frustrating. This is a problem that has arisen since the 3.1 firmware upgrade. I would say that 9 times out of ten the audiobook does not save my place, and resets to chapter 1. This is a proper audiobook file, “remember position” is set to yes.

This is 20 something hour book… (Eye of The World: Robert Jordan) and I would like to listen to it without worry.
