iPhone SDK: Programs Won't Run in the Background

Silicon Alley Insider and others are throwing a little cold water on the iPhone SDK by pointing out a very important limitation of the SDK:

"Only one iPhone application can run at a time, and third-party applications never run in the background. This means that when users switch to another application, answer the phone, or check their email, the application they were using quits. (p. 16)"

That is really bad news. That means my dream VoIP scenario of receiving calls at home won't work because I'd always have to launch the program and keep it open while at home--too much of a bother.
