Books for preparing for Cisco Unity Exam??

[esanvalero]

Hello, please I would like to know if there is any official book or preparation guide for the Unity exam, from cisco press or any other.

Another question, which exam is preferrable for Unity, (UCSE)1.x (#644-101) (for Unity 4.x)

or #9E0-805 UNITY, (for Unity 3.x)?

Please help, i haven't found any!

Thanks

Exam 644-101 is the latest rev.

There are no official books available for exam preparation, although there are training classes.
