I upgraded to iOS 5 on my iPhone 4 and now I cannot play audiobooks correctly. When I transfer audiobooks to my phone using Overdrive they show up in the book section but are unable to play. I have to designate each file as Music to be able to play them, but then I am not able to listen to them in chapter format, nor am I able to play in double speed or use the 30 second fast forward button. I spend more time listening to books on my phone than anything else so this is a major digression in capability.
Is there a fix to this?
