Xcode and the other tools provide all the same features you would expect of any Integrated development environment

The simulator allows you to immediately test and run most applications, with the notable exception of OpenGL ES code.

This means you are able to do development without an iPhone

iPhone SDK - Acceptance

The acceptances appear to be random. At least some people who could be considered relative programming novices have been accepted, while some large companies have not.

The program is firewalled. Unless you are authorized, you will not get access to Apple's documentation and support site.

Five iPhone limit. You may develop for up to five iPhones and that's it.

Test devices are just that. Adding the pre-release iPhone OS to your iPhone seems to kill actual phone functionality.
