Watch the WWDC 2010 video sessions 105 and 109: Adopting Multitasking on iPhone OS, Parts 1 and 2. The iOS 4.0 application life cycle is displayed several times in those presentations and is described in detail.

See also the "Application Life Cycle" section of the iPhone Application Programming Guide.
