iPhone

iPhone:

The iPhone is a multimedia and Internet-enabled quad-band GSM EDGE-supported mobile phone designed and marketed by Apple Inc. The iPhone's functions include those of a camera phone and a portable media player ("iPod"), in addition to text messaging and visual voicemail. It also offers Internet services including e-mail, web browsing, and local Wi-Fi connectivity. User input is accomplished via a multi-touch screen with virtual keyboard and buttons.
The iPhone has been available since June 29, 2007 in the United States from Apple retail and online stores, and from AT&T Mobility. The current price is US$399 for an 8 GB model. On September 18, 2007, Apple announced in a special event that the iPhone will be available on November 9, 2007 on the carrier O2 in the United Kingdom. On September 19, 2007, Apple and Deutsche Telekom's T-Mobile announced the iPhone would go on sale November 9, 2007 throughout Germany. On October 16, 2007, Apple confirmed that France Télécom's Orange would be the exclusive carrier for the iPhone in France with a release date of November 29, 2007. On October 24, 2007 as a result of a Molson contest, Canadian newspaper The Globe and Mail revealed that Rogers Wireless may begin offering the iPhone in Canada starting sometime in 2008, however no official statement has been released by Apple or Rogers confirming this.

History:

The genesis of the iPhone began with Jobs's direction that Apple engineers investigate touch-screens. At the time he had been considering having Apple work on tablet PCs.

Comments made by Jobs in April 2003 at the "D: All Things Digital" executive conference expressed his belief that tablet PCs and traditional PDAs were not good choices as high-demand markets for Apple to enter, despite many requests made to him that Apple create another PDA. He did believe that cell phones were going to become important devices for portable information access.

On January 9, 2007, Jobs announced the iPhone at the Macworld convention, receiving substantial media attention, and on June 11, 2007 announced at the Apple's Worldwide Developer's Conference that the iPhone would support third-party applications using the Safari engine on the device. Third-parties would create the Web 2.0 applications and users would access them via the Internet. On October 17, 2007 Apple announced that an iPhone software development kit would be made available in Feburary 2008.

According to The Wall Street Journal, the iPhone is manufactured on contract in the Shenzhen factory of the Taiwanese company Hon Hai.

Features:

The iPhone allows conferencing, call holding, call merging, caller ID, and integration with other cellular network features and iPhone functions. For example, a playing song fades out when the user receives a call. Once the call is ended the music fades back in. Voice dialing is not supported by the iPhone.

The iPhone includes a Visual Voicemail feature allowing users to view a list of current voicemail messages on-screen without having to call into their voicemail. Unlike most other systems, messages can be listened to and deleted in a non-chronological order by choosing any message from an on-screen list. AT&T modified their voicemail infrastructure to accommodate this new feature designed by Apple.

A ringtone feature, introduced on September 5, 2007, allows users to create custom ringtones from their purchased iTunes music for an additional fee, the same price of a song. The ringtones can be from 3 to 30 seconds in length of any part of a song, can include fading in and out, can pause from half a second to five seconds when looped, and never expire. All customizing can be done in iTunes, and the synced ringtones can also be used for alarms on the iPhone.
Apple has released a video explaining many of iPhone's features through a series of demonstrations.

Text messaging:

Text messages are presented chronologically in a mailbox format similar to Mail, which places all text from recipients together with replies. Text messages are displayed in speech bubbles (similar to iChat) under each recipient's name. The iPhone does not support instant messaging, MMS, multi-recipient SMS, or copy/cut/paste capability.

Camera:

The iPhone features a built in 2.0 megapixel camera located on the back for still digital photos, but not video recording. It also includes software that allows the user to upload, view, and e-mail photos. The user zooms in and out of photos by "unpinching" and "pinching" them through the multi-touch interface. The software interacts with iPhoto on the Mac.

Multimedia:

The layout of the music library differs from previous iPods, with the sections divided more clearly alphabetically, and with a larger font. Similar to previous iPods, the iPhone can sort its media library by songs, artists, albums, videos, playlists, genres, composers, podcasts, audiobooks, and compilations. The Cover Flow, like that on iTunes, shows the different album covers in a scroll-through photo library. Scrolling is achieved by swiping a finger across the screen.

Like the fifth generation iPods introduced in 2005, the iPhone can play video, allowing users to watch TV shows and films. Unlike other image-related content, video on the iPhone plays only in the landscape orientation, when the phone is turned sideways. Double tapping switches between wide-screen and fullscreen video playback.

The iPhone allows users to purchase and download songs from the iTunes Store directly to their iPhone over Wi-Fi, but not over the cellular data network.

Web connectivity:

The iPhone has built-in Wi-Fi, with which it is able to access the World Wide Web (through a wireless network) via a modified version of the Safari web browser. The iPhone is also able to connect to the web through AT&T's EDGE network, but is not able to utilize AT&T's 3G/HSDPA network; Steve Jobs mentioned at the Keynote presentation that 3G support would be a future feature of a new version. The use of the EDGE network instead of 3G has been criticized by analysts. When the user is not in a Wi-Fi hot spot, the iPhone's network connection will use the older EDGE network; before the launch, reviewers found that the EDGE network was "excruciatingly slow," with the iPhone taking as long as 100 seconds to download the Yahoo! home page for the first time. Immediately before the launch the observed speed of the network increased to almost 200 kbit/s. This is probably due to the new "Fine EDGE" upgrades AT&T has been making to their network prior to the launch. The EDGE network does benefit iPhone users by providing greater availability than 3G, although 3G continues to be expanded to most major cities in the United States. The iPhone does not provide tethering for laptop users.
The web browser displays full web pages as opposed to simplified pages as on most non-smartphones. The iPhone does not support Flash or Java technology. Web pages may be viewed in portrait or landscape mode and support automatic zooming by "pinching" or double-tapping images or text. The iPhone also has Bluetooth 2.x+EDR built in, which only works with wireless earpieces that use Bluetooth technology, but does not support A2DP or common Bluetooth file transfer (OBEX).

An agreement between Apple and Google provides for access to a specially modified version of Google Maps—in map, local list, or satellite form, optimized for the iPhone, which also provides optional real-time traffic information. During the product's announcement, Jobs demonstrated this feature by searching for nearby Starbucks locations and then placing a prank call to one with a single tap. Google's ownership of YouTube means that viewing videos on the website can be achieved on the iPhone through a specialised application built into the system.

E-mail:

The iPhone also features an e-mail program that supports HTML e-mail, which enables the user to embed photos in an e-mail message. PDF, Microsoft Word, and Microsoft Excel attachments to mail messages can be viewed on the phone. Yahoo! is currently the only e-mail provider offering a free Push-IMAP e-mail service similar to that on a BlackBerry for the iPhone; IMAP and POP3 mail standards are also supported, including Microsoft Exchange. However, there is currently no search support. The iPhone will sync e-mail account settings over from Apple's own Mail application, Microsoft Outlook and Microsoft Entourage, or can be manually configured using the device's Settings tool. With the correct settings, the e-mail program can check many IMAP or POP3-enabled web based accounts such as Gmail, .Mac mail, and AOL.

Interface:

The iPhone's touch interface has been compared by some media to the HTC Touch, which also features a touchscreen designed for fingers, although it can also be used with a stylus and lacks multi-touch.

The display responds to three sensors: a proximity sensor that shuts off the display and touchscreen when the iPhone is brought near the face to save battery power and to prevent spurious inputs from the user's face and ears, an ambient light sensor that adjusts the display brightness which in turn saves battery power, and a 3-axis accelerometer, which senses the orientation of the phone and changes the screen accordingly. Web browsing and music playing support three orientations, while videos play in only one widescreen orientation.

A single "home" hardware button below the display brings up the main menu. Subselections are made via the touchscreen. The iPhone utilizes a full-paged display, with context-specific submenus at the top and/or bottom of each page, sometimes depending on screen orientation. Detail pages display the equivalent of a "Back" button to go up one menu.

The iPhone has three physical switches on its sides: sleep / wake, volume up / down, ringer on / off. All other multimedia and phone operations are done via the touch screen.

Text input:

For text input, the device implements a virtual keyboard on the touchscreen. It has automatic spell checking and correction, predictive word capabilities, and a dynamic dictionary that learns new words. The predictive word capabilities have been integrated with the dynamic virtual keyboard so that users will not have to be extremely accurate when typing—i.e. touching the edges of the desired letter or nearby letters on the keyboard will be predictively corrected when possible. The keys are somewhat larger and spaced further apart when in landscape mode (currently, only using Safari). Not focusing more on texting has been considered a chief weakness of the iPhone, while at the same time the virtual keyboard is a bold step and a worthwhile risk.

David Pogue of The New York Times and Walt Mossberg of The Wall Street Journal both tested the iPhone for two weeks and found learning to use it initially difficult, although eventually usable. Pogue stated use was "frustrating" at first, but "once you stop stressing about each individual letter and just plow ahead, speed and accuracy pick up considerably." After five days of use, Mossberg "was able to type on it as quickly and accurately as he could on the Palm Treo he has used for years," and considered the keyboard a "nonissue." Both found that the typo-correcting feature of the iPhone was the key to using the virtual keyboard successfully.
The iPhone interface enables the user to move the content itself up or down by a touch-drag motion of the finger, much as one would freely slide or flick a playing card across a table with a finger. Similarly, scrolling through a long list in a menu works as if the list is pasted on the outer surface of a wheel: the wheel can be "spun" by sliding a finger over the display from bottom to top (or vice versa). In either case, the object continues to move based on the flicking motion of the finger, slowly decelerating as if affected by friction. In this way, the interface simulates the physics of 3D objects, giving it a real world feel.

The photo album and web page magnifications are examples of multi-touch sensing. It is possible to zoom in and out of web pages and photos by placing two fingers (e.g. thumb and forefinger) on the screen and spreading them farther apart or closer together, as if stretching or squeezing the image. As can be expected from multi-touch sensing, the two fingers don't have to be from the same hand.
