I have used the Audible app on my ipod touch without any problems. I am now using an iphone 4 and have downloaded the Audible app however I am unable to see the audio books I have in My Library. I have signed in and out a couple of times with no affect. Why can I not see them as I want to download a couple onto my phone. I have checked all their suggestions, I only have one username, signed into UK location and have ALL Titles for the whole year.
