Has any one ever installed manilla 2d onto a ppc 6700? If so, can you give me detailed instructions on how to do it? Also, can I install it on my storage card because there's not enough space on the phone itself?

You'll probably have to install a stripped down rom.
You can find some here:

And here's a post on making it work on the Apache aka ppc 6700
