The iPhone/iPod touch version of Delicious Library has been pulled because it ran afoul of Amazon’s terms of service. This is a real pity, because the iPhone/iPod touch version of Delicious Library is fantastic. It syncs up with the desktop version via WiFi (sidestepping the iTunes sync), downloading your collection data onto your device. This is extremely handy when you have an iPod touch, because it means you don’t need a network connection to browse your own library — and browsing your own library is really handy in a bookstore when you’re trying to remember if you already own a book. Really well-implemented search, too. So: a real pity. Good thing it can’t be undownloaded — I’ve already got mine, and I won’t give it up!
