The complexity and sophistication has come down to stay in the palms in terms of an iPhone. The most advanced operating system in the world, the OS X gives the reflection of a true desktop for the user. This thereby include the functioning of softwares like HTML email, full-featured web browsing, and applications such as widgets, Safari, calendar, text messaging, Notes, and Address Book.

The downloading of an email on an iPhone doesnt stop a user from surfing the web in any sense. Apple iPhone uses quad-band GSM, the global standard for wireless communications. It also supports Cingulars EDGE network, 802.11b/g Wi-Fi, and Bluetooth 2.0 with EDR, which links to Apples new, remarkably compact Bluetooth headset.

The iPhone's processor has been reported to be ARM, and the OS X version differs in some ways from the ones that run on the desktop. This being said, it seems logical to explain the fact that since the uses are modified to a massive extent- the platform had to be modified in some senses.

The operating system takes up about 700 MB of the device's total 4 or 8 GB storage. The build of OS X on at least one iPhone is "OS X 1.0 (1A543a)", as seen in a crash log for the Mobile Mail application.

The version of OS X which is used in the iPhone includes a software component "Core Animation" which helps in supporting the smooth animations for better human interface.
