For students, a textbook with that iPhone?

The Apple (AAPL) iPhone App store already has over 60,000 products and one billion downloads. It is about to get a new set of products that should do especially well. iPhone users will be able to download up to 7,000 different textbooks onto their handsets, making "education everywhere" a reality.

According toThe Wall Street Journal, CourseSmart LLC, a joint venture between McGraw-Hill (MHP) and Pearson, believes that it can use the iPhone to jump start the nascent e-textbook market.
