Answer 1

It depends on the application. I am focused on games, so my target devices are 3G and iPod Touch (not the new one). Something older may be quite too restrictive for some ideas... At some point I will switch to the new 'retina display' models. But not now: the cake is still way too big with the not-so-old models!

Nevertheless, Apple forces you to use the latest XCode (4.1 devices). However, while you are forced to use the latest SDK, you may still target older devices (3.0 in our case, for example). You may go back to 2.1.1 devices, if I remember well.

Good luck!
