Hey Gordio, sorry to hear about your layoff. That's one of the reasons I got into iOS programming as a hobby while I'm still employed; there's been plenty of layoffs at my work over the last few years and it never hurts acquiring new skills. It happens to be fun too!
This book and the Learn Cocos2D book are great resources. I just ordered the Beginning iOS5 Programming book by Apress and am hoping that it's a good book to get me up and running with apps.
I'm using the accelerometer in my current game and can't wait to get it done. The basic structure is there but I'm working on the menu system and the different levels.
I think after I finish the next game I'm working on, I am going to try my hand at an app or two and not a game, just to get my feet wet there.
