About: iPhone is a smartphone made by Apple that combines an iPod, a tablet PC, a digital camera and a cellular phone. The device includes Internet browsing and networking capabilities

iPhone is extremely thin (only 11.6 millimeters thick) but wider and longer than many comparable devices. The display area is a 3.5-inch wide screen multi-touch interface with unusually high resolution (160 pixels per inch). Unlike most other smart phones, iPhone does not use a hardware keyboard or a stylus. To navigate, a user uses multiple taps and drags to navigate through a mobile version of Apple's OS X operating system. Like iPod, iPhone synchronizes data with a user's personal computer, using iTunes as client software and Apple's proprietary USB port. iPhone 3GS also features a fingerprint-resistant oleophobic coating. iPhone is compatible with Microsoft's Windows operating systems, including Vista.
iphone features:
1. The touch screen is a 9 cm (3.5 in) liquid crystal display (320×480 px at 6.3 px/mm, 163 ppi, HVGA) with scratch-resistant glass,[24] and 18-bit color (rendering 262,144 colors). The capacitive touch screen is designed for a bare finger, or multiple fingers for multi-touch sensing.
2. The bottom of the iPhone sports a speaker (left) and a microphone (right) flanking the dock connector. One loudspeaker is located above the screen as an earpiece, and another is located on the left side of the bottom of the unit, opposite a microphone on the bottom-right. The iPhone 4 includes an additional microphone at the top of the unit for noise cancellation, and switches the placement of the microphone and speaker on the base on the unit—the speaker is on the left.[38] Volume controls are located on the left side of all iPhone models and as a slider in the iPod application. Both speakers are used for hands free operations and media playback
3. The iPhone features an internal rechargeable battery. Like an iPod but unlike most other mobile phones, the battery is not user-replaceable.The iPhone can be charged when connected to a computer for syncing across the included USB to dock connector cable, similar to charging an iPod.
4. The iPhone and iPhone 3G feature a built-in fixed focus 2.0 megapixel camera located on the back for still digital photos. It has no optical zoom, flash or autofocus, and does not support video recording, however jail breaking allows users to do so. Version 2.0 of iPhone OS introduced the capability to embed location data in the pictures, producing geocoded photographs.
5. The iPhone was initially released with two options for internal storage size: 4 GB or 8 GB.
6. the iPhone has moisture sensors to indicate whether water damage has affected a device.
iPhone's networking features include:
Automatic detection of WiFi networks.
Support for the 802.11b and 802.11g standards.
The use of quadband GSM and SIM cards to access cellular networks.
EDGE support for high-speed data transfer where available.
Bluetooth connectivity for short range networking with peripherals, other iPhones and PCs.
Apple says that iPhone carries 8 hours of life on the internal lithium-ion battery for talk or video, and up to 24 hours for music mode. The device ships with either a 4 or 8 GB hard drive, an Intel CPU and Apple's OS X operating system, modified for mobile use.
iPhone comes preloaded with a suite of media management software and communications software, including iTunes, the Safari Web browser and iPhoto. iPhoto may be used in combination with the 2 megapixel camera on the back of the device. Google's search and mapping services are fully integrated, including the ability to initiate phone calls from within Google Maps. Users can also view YouTube videos on the device, along with Microsoft Office documents and most imaging formats, including .JPEG, .GIF and .TIFF. A partnership with Yahoo allows iPhone users to send and receive rich HTML email. Other IMAP or POP3 e-mail services are integrated as well, along with webmail access in the browser.

History: The first iPhone was introduced on January 9, 2007.
There have been four generations of iPhone hardware, and they have been accompanied by four major releases of iOS (formerly iPhone OS). The original iPhone established design precedents like screen size and button placement that have persisted through all models. The iPhone 3G brought 3G cellular network capabilities and A-GPS location. The iPhone 3GS brought a compass, faster processor, and higher resolution camera, including video. The iPhone 4 has two cameras for FaceTime video calling and higher resolution display. It was released on June 24, 2010 in certain countries and is in the process of being released worldwide.
Here is where the iPhone 4 will turn up first:
Germany: Deutsche Telekom AG (NYSE: DT) retains its exclusive relationship with Apple and will be the only operator to support the new device in the country at the end of this month. (See Vodafone’s iPhone Envy.)
France, Bouygues Telecom, Orange France (Paris: OGE), and SFR will carry the iPhone 4.
The UK: O2 (UK) Ltd. , Orange UK , and Vodafone UK will all carry the device and it will also be available for purchase from phone retailers Carphone Warehouse Group plc (London: CPW) and Phones 4U.
Japan: SoftBank Corp. will offer the iPhone 4.
The US: AT&T Inc. (NYSE: T) remains the sole carrier for the iPhone.
“We’ll see all the operators embracing iPhone 4,” says Wood. “But they have to make sure they don’t relinquish all control to Apple and have it take over their portfolios.”

1.7 million Units sold in five countries.

Why only Five Countries:
The new iPhone will soon crop up in many more international markets as well. Not only will Apple launch the device in five countries simultaneously this month, but it will also take the new iPhone to 18 more countries by end of July and a total of 88 countries by the end of September.
Reason: 1. Struggle to keep the huge initial demand.
2. Check marked improvement in Apple’s distribution systems
Disadvantage: Signal problem if grabbed hard.
1.After being redirected to a conversation to the ipad the alarm starts buzzing in terror and can shock the user.
2. Exhibiting areas of brown or yellow discoloration on the highly-touted Retina display.
3. The biggest complaint to emerge is that the phone's signal strength drops from 5 to 1 when a user grips the phone by the metal antenna band.
Solution: To fix this, they are adopting AT&T’s recently recommended formula for calculating how many bars to display for a given signal strength. The real signal strength remains the same, but the iPhone’s bars will report it far more accurately, providing users a much better indication of the reception they will get in a given areas.They are also making bars 1, 2 and 3 a bit taller so they will be easier to see.
They will issue a free software update within a few weeks that incorporates the corrected formula. Since this mistake has been present since the original iPhone, this software update will also be available for the iPhone 3GS and iPhone 3G.
Update: There have been new developments regarding both the discoloration issue and the reception issue. According to Engadget and others, the yellow time sometimes goes after a day or two. Heat seems to affect the discoloration, and it may be due to a bonding agent known as Organofunctional Silane Z-6011, which Apple may be using to bond the iPhone 4’s glass together. If it’s not fully dry (say, due to a rapid pace of production), it could possibly cause discoloration.
The reception issue is real, though, but the question is whether it’s a software or a hardware bug. Boy Genius Report seems to think the issue is a software problem because some iPhone 4s can still make calls, despite displaying zero bars. Putting a bumper or cover on your phone though seems to solve the issue.
