The TOC on Tapworthy - designing great iPhone Apps (http://shop.oreilly.com/product/06369...) is wrong!
It's for a networks book (types of network connections / hubs, switches etc.).
Thanks for taking the time to let us know about this! We'll remove the incorrect TOC, and as you noted, you can preview the contents in the Google Preview, and you can also preview it on Safari Books Online.
Sorry for the confusion, and thanks again for letting us know.
