The iPhone 5 will be announced on October 4, 2011, and by the end of September there are many rumors of iPhone 5, the iPhone 5′s details (with a 4-inch touch screen, dual-core processor, two cameras (one on the back and one on the front for video calling), at least 16GB of built-in storage, Bluetooth, GPS and a LED sensor) are based off of rumored specs, but considering the previous enhancements the handset has received they seem fairly feasible. But I think most of the key rumor source from an infographic about the evolution of iPhone.

Evolution of “The iPhone”, from iPhone to iPhone 5 [infographic]

Since the launch of the first iPhone on January 9th 2007, Apple has gone a long way. Till now only four iPhone models have been unveiled, each of which was a smashing hit for the company. And now with the next generation iPhone 5coming up, there are no doubts that it is going to bring a lot of fortune to the company.

iOS1 was the first operating system introduced in the first iPhone that was launched in 2009. iOS2 the second major release of Apple became available with the release of the iPhone 3G. Devices that were previously running iOS1 were upgradable to this new version. This version of the OS introduced the App Store, making third-party applications available to the iPhone and iPod touch.

iOS3 became available with the release of iPhone 3GS. It was released on June 17, 2009. This release added much requested features such as copy and paste, and MMS. Then came the iOS4; it was made public for the iPhone and iPod touch on June 21, 2010. This is the first major iOS release to drop support for some devices.

Now with the upcoming release of iphone5 Apple has introduced a new, upgraded operating system, iOS5. For this iOS version 5.0, USB connection to iTunes and activating iOS devices is no longer required. Data synchronization happens automatically and wirelessly through Apple’s new iCloud service.

Initially, Apple supported web-based apps only, but later allowed third party apps to be downloaded to through the Apple store. The original iPhone lacked 3G radio and GPS, two things that were later in its successor – iPhone 3G.

With the release of iPhone 4, more advances were made in the device. The iPhone 4 is the thinnest smart phone ever with all-new design, Face Time video calling, Apple’s stunning new Retina display, 5 megapixel camera and HD video recording.

The iPhone 5 is a successor,for Google android Smartphone, the rumors have been swirling for months that the next version of Google's Android operating system, to be nicknamed Ice Cream Sandwich, will make its debut on a new Samsung Smartphone which could be called the Nexus Prime., it is expected on the back of iPhone 5

And for the China Hiphone market, I think Hiphone 5 will follow the trend of iphone, but I think there is also some new revolution, let’s expecting.
