Bought the wrong book, Valuable resource?

Just looked on the website and the current CCNA Voice exam is 640-461 ICOMM
But the book I have bought is this:
[h=3]CCNA Voice Study Guide: Exam 640-460 by Andrew Froehlich[/h]
absolutely gutted,
Does anyone know if this is still a valuable resource?

Definitely get the new book. It's only $30 on Amazon.
Excellent, can crack on with this now.
