Milind Alvares on iPhone OS Multitasking

Milind Alvares:

The iPad (and the iPhone) supports background processes. It supports multiple processes, and it can do this without any adverse effects on your battery life. This capability however, is reserved for built-in applications, and not for third-party applications.

One small clarification: rather than “third-party”, I’d say “App Store applications”. Apple’s built-in iPhone OS system apps do all sorts of things the SDK doesn’t allow, but Apple’s iPhone apps distributed through the App Store all seem to play by the App Store rules. It’s system vs. App Store, not Apple vs. third-party.
