iPhone OS. No seriously it's actually called iPhone OS.
The OS 8 is for the iPhone 4. The iPhone 4 is a really popular phone.
The iPhone, along with the iPod Touch and iPad, run iOS, previously called iPhone OS.
It runs a pared down version of Mac OS X with a FreeBSD sub-system. It also operates over a Darwin Kernel for those who are interested.
The iPhone software development kit (SDK) only runs on recent versions of Mac OS X. The cheapest solution (short of trying to hack OS X to run on your PC) is to by a Mac Mini.
The iPhone OS 4.0 will be available to iPhone and iPod Touch owners for download through iTunes during the summer of 2010.

Both Windows and the iPhone OS are operating systems in which they provide an interface between software and hardware, but that's where the similarities end. The iPhone OS is designed specifically for Apple's iPhone, iPod Touch, and iPad mobile devices, and runs a modified Darwin Linux kernel. The same base operating system (Darwin) is also found on the Mac OS X operating system, albiet modified for use on a personal computer. The iPhone OS is also designed to be run on a system that contains an ARM processor. It currently cannot be run on any other system, except the iPhone Simulator contained within the iPhone SDK. The Windows family of operating systems is a more generalized operating system designed primarily for consumer desktop and laptop computers, although specialized versions for mobile phones and other embedded devices exist. Unlike the iPhone OS, Windows is able to be run on a wider variety of processors including Intel, AMD, and in the case of older Windows operating systems; PowerPC, Alpha, and MIPS processors.
