First up, Craig Hockenberry (he of Iconfactory fame) has released a book about iPhone OS development. At this point you're probably saying "Another book about developing for the iPhone? Really we don't have enough?" The thing is that apart from the constant updating of the OS Apple does which always makes new books and new editions interesting, Hockenberry takes you through the whole development/submission/approval process to getting your app into Apples App Store. Of course there's lots of Xcode/Cocoa goodness as well but so far it's reading more like the business of app development - which is a win for me and I'm sure many other.
The best way to get it, IMHO, is via the O'Reilly's bundle which gets you the hard copy and the e-book. Just watch out for O'Reilly's discount mechanisms otherwise you could end up pay more than you need or want to.
Yes after a long wait Delicious Library 2 has Arrived! You can get it
I've been described as a lost technocrat or a wondering luddite, personally I just like everything that takes us forward.
