I've been digging around the net recently and noticed some video tutorials show an older template (pre SDK 3.2) with one OpenGL ES context. Now there are two of them, which, I've gleaned are the two versions of OpenGL ES available on the newer iMobile devices.

Can I just use the older one or do I need to do everything twice? How do I tell the iPhone to use the older context, or will it do so automatically?
