In six days from now on iPhone will be on the store shelves and the Apple’s promised mobile revolution will be ready to begin.

Since its introduction back in January during Jobs’ opening speech at WWDC, iPhone captured a lot of attention and even few are those who really have seen the device, everybody seems to have an opinion.

But what we know so far? Apple said that the 4 gigabyte version will cost 499 dollars and the 8 gigabyte version will be sold for 599 dollars. The device features a touch-screen input technology called Multi- Touch, controlled by sliding a finger across its touch-sensitive, 9-centimeter (3.5-inch), 160-pixel-per-inch display. The display automatically switches between landscape or portrait mode thanks to a built-in sensor.

The 11.6-millimetre thick device also sports a 2-megapixel camera, headset jack, 3.5-millimetre audio jack, SIM tray, a sleep-wake switch, speaker, microphone and an iPod dock connector. The quad-band GSM plus EDGE phone also has Wi-Fi and Bluetooth 2.0 capabilities.

Will iPhone revolutionize the mobile market? Many analysts are certain that iPhone will change what consumers expect from the mobile phones, but still is hard to say if Apple will win the battle with the traditional mobile phone makers, such as Nokia, Motorola or Samsung.

In fact, there are already mobile phones that are trying to offer the same touch-screen technology and same features as the iPhone.

HTC announced two weeks ago HTC Touch, Sony Ericcsson introduced two new Walkman phones W960 and W910 so it seems iPhone will have to face a tough competition. Apple is aware of how important is iPhone for its future and in its latest update the company said it upgraded the entire top surface of the phone, including its 3.5-inch display, from plastic to optical-quality glass to achieve a superior level of scratch resistance and optical clarity.

Also iPhone will feature up to 8 hours of talk time, 6 hours of Internet use, 7 hours of video playback or 24 hours of audio playback.

But the true power of iPhone is not the hardware, but the software. iPhone is the first phone based on Mac OS and this could mean a real advantage in front of its competitors.

Due to its advanced software features, iPhone may change the way people interact with their phones and this could be the real Apple’s bet.

Revolutionary or not, iPhone has already created a real buzz. AT&T, the company which will sell iPhone in an exclusive deal, said 1.1 million potential customers had signed up on the Web site asking to be contacted when the phone is for sale.

In fact AT&T is so sure about the consumer interest they have hired an extra 2,000 temporary employees just to handle the iPhone launch.

In a research released earlier this month M:Metrics, a market research firm, said that 64 percent of American mobile phone users had heard of the iPhone and 14 percent of those would be “highly interested in buying one.”

In his speech at WWDC, Steve Jobs said Apple hopes to sell 1 million iPhones until 2008. If Apple will meet its target it remains to be seen, but iPhone already forced the mobile phone makers to release new models with new features. Let’s hope that in six days iPhone will prove it has worth the wait and the hype!
