I got hold of a copy of this book from a friend who works at Vodafone, and who is running a "side business" selling pictures of trains & busses for mobiles.
It basically is a "cookbook" that steps you through how to make a WAP site - I hosted mine on geocities - and then configure it so that users visitin the site can pay you money when they download your files, pictures, whatever.
It gives marketing tips, but to be honest these are not the main idea of the book - its more how to make the cake and sell it rather than how to get lots of people coming to your cake stall.
I got my site (improve your health through vinegar) going last week, and I've already made back about £30 in revenue just by registering with the free Bango directory - so if I had bought the book it would have paid for itself.
Mr Smith's magic is to explain what to do in a way a mobile / WAP novice like me can follow - and it works!
I'd like a bit more on the ways to encode images and on handset differences etc., but the book has already passed on to its next owner who wants to build a "gamer's tips" site ....
