Speaking of  the importance of having a human element associated with programming, I’ve been listening to a number of excellent iPhone / Cocoa podcasts that you might enjoy. Over the past few months I’ve tried 10+ podcasts, and whittled it down to ones I found especially interesting. Sometimes it is a bit difficult to figure out what the person is talking when only hearing audio. For introductory tutorials I still recommend videos, but podcasts are a great way to hear the in-depth minutia that actual developers in the field are talking about.

Mobile Orchard: iPhone Developer Podcast
http://www.mobileorchard.com/
Interviews with some of the leading iPhone developers. Previous guests include developers responsible for Weightbot, NetNewsWire, the Pandora iPhone Player, and others.

Late Night Cocoa
http://www.mac-developer-network.com/category/podcasts/lnc/ 
Geared more towards Cocoa developers in general, this is one of my favorite podcasts right now. Started by a developer trying to learn Cocoa, he brings on really knowledgeable guests who break down technical subjects in a manageable way.

CocoaCast

The recording quality is a bit aggravating at times, but these guys really know their stuff. They are very experienced developers who have very detailed conversations about Cocoa. Not for the feint of heart (or beginners who don’t have the patience to figure out what they’re talking about).
