In the spirit of paying it forward, I want to pass on this bit of info if you have a 8900 on ATT and want to transfer your Audible to it.
I spent a total of two hours on the phone w/the people at audible, and while they were very nice, at the end of the day, she had to tell me she had no clue why I kept getting the 'unable to connect' message.
I finally went into the tcp section of my old phone (options/advanced) and noticed that my old phone (8110) did not say "proxy", as they told me to put in it said wap.cingular.
I changed that on my new phone and poof--I connected and got my books.
