Will the 30D Field Guide work with the 40D?

[JSB3]

I recently purchased a 40D. It should be arriving within the next week. My question...
Will the 30D Field Guide work with the 40D? Ie... Are most of the funcitons the same?
I want to get the Field Guide for the 40D but it is not released until March 2008.
Or does anyone have any suggestions for a good beginners guide to the operation of the 40D.
Thanks

(I have never owned a DSLR before, however I have used my Brothers Nikon D80. He has a book titled the D80 Field Guide. To me it is very straightforward and easy to understand. )

I wouldn't, the menus and functions of the 40D are different enough that it probably wouldn't be worth buying the 30D guide.

I learned everything I needed to know off of this forum. ;)
