I've been successfully using the Audible app on an iPhone 5 since beta 1. What issue were you having?

Under Beta 1, I could not control Audible using Control Center or using the headset. Once that was fixed, Audible would then crash during the refresh every time it launched. The current release of Audible resolves both of those.

Headset control was an issue for all apps and was resolved in Beta 5. Good you've got Audible working now though...Iisten to it all day so I can appreciate that would suck if it wasn't working!
