This is the one – MP3 Audiobook Player Pro Review

Been looking for the best way to listen to audiobooks on iPhone and still have control over my own data. Finally.... this is the one. Works great with MP3s and M4Bs and I can sideload into the app right over WiFi and I could even setup a network share to the app folder.
