Software

The iPhone (and iPod Touch) run an operating system known as iOS (formerly iPhone OS). It is a variant of the same Darwin operating system core that is found in Mac OS X. Also included is the "Core Animation" software component from Mac OS X v10.5 Leopard. Together with the PowerVR hardware (and on the iPhone 3GS, OpenGL ES 2.0), it is responsible for the interface's motion graphics. The operating system takes up less than half a GB of the device's total storage (4 to 32�GB). It is capable of supporting bundled and future applications from Apple, as well as from third-party developers. Software applications cannot be copied directly from Mac OS X but must be written and compiled specifically for iOS. Like the iPod, the iPhone is managed with iTunes. The earliest versions of the OS required version 7.3 or later, which is compatible with Mac OS X version 10.4.10 Tiger or later, and 32-bit Windows XP or Vista.

Interface

The interface is based around the home screen, a graphical list of available applications. iPhone applications normally run one at a time (not including iOS 4, which includes running applications in the background Users can also add and delete icons from the dock, which is the same on every home screen. Each home screen holds up to sixteen icons, and the dock holds up to four icons. Users can delete Web Clips and third-party applications at any time, and may select only certain applications for transfer from iTunes. Apple's default programs, however, may not be removed. The 3.0 update adds a system-wide search, known as Spotlight, to the left of the first home screen. Almost all input is given through the touch screen, which understands complex gestures using multi-touch. The iPhone's interaction techniques enable the user to move the content up or down by a touch-drag motion of the finger. For example, zooming in and out of web pages and photos is done by placing two fingers on the screen and spreading them farther apart or bringing them closer together, a gesture known as "pinching". Scrolling through a long list or menu is achieved by sliding a finger over the display from bottom to top, or vice versa to go back. In either case, the list moves as if it is pasted on the outer surface of a wheel, slowly decelerating as if affected by friction. In this way, the interface simulates the physics of a real object. Other user-centered interactive effects include horizontally sliding sub-selection, the vertically sliding keyboard and bookmarks menu, and widgets that turn around to allow settings to be configured on the other side. Menu bars are found at the top and bottom of the screen when necessary. Their options vary by program, but always follow a consistent style motif. In menu hierarchies, a "back" button in the top-left corner of the screen displays the name of the parent folder.

Phone

The iPhone allows audio conferencing, call holding, call merging, caller ID, and integration with other cellular network features and iPhone functions. For example, if music is playing when a call is received, the music fades out, and fades back in when the call has ended. The proximity sensor shuts off the screen and touch-sensitive circuitry when the iPhone is brought close to the face, both to save battery and prevent unintentional touches. The iPhone does not support video calling or videoconferencing on versions prior to the 4th generation, as there is only one camera on the opposite side of the screen. The iPhone includes a visual voicemail (in some countries) 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. A music ringtone feature was introduced in the United States on September 5, 2007. Users can create custom ringtones from songs purchased from the iTunes Store for a small additional fee. The ringtones can be 3 to 30 seconds long from any part of a song, can fade in and out, pause from half a second to five seconds when looped, or loop continuously. All customizing can be done in iTunes,

Multimedia

The layout of the music library is similar to that of an iPod or current Symbian S60 phones. The iPhone can sort its media library by songs, artists, albums, videos, playlists, genres, composers, podcasts, audiobooks, and compilations. Options are always presented alphabetically, except in playlists, which retain their order from iTunes. The iPhone uses a large font that allows users plenty of room to touch their selection. Users can rotate their device horizontally to landscape mode to access Cover Flow. Like on iTunes, this feature shows the different album covers in a scroll-through photo library. Scrolling is achieved by swiping a finger across the screen. Alternatively, headset controls can be used to pause, play, skip, and repeat tracks. On the iPhone 3GS, the volume can be changed with the included Apple Earphones, and the Voice Control feature can be used to identify a track, play songs in a playlist or by a specific artist, or create a Genius playlist. . The iPhone supports gapless playback. Like the fifth generation iPods introduced in 2005, the iPhone can play digital video, allowing users to watch TV shows and movies in widescreen. Double-tapping switches between widescreen and fullscreen video playback. The iPhone allows users to purchase and download songs from the iTunes Store directly to their iPhone. The feature originally required a Wi-Fi network, but now can use the cellular data network if one is not available. The iPhone includes software that allows the user to upload, view, and e-mail photos taken with the camera. The user zooms in and out of photos by sliding two fingers further apart or closer together, much like Safari. The Camera application also lets users view the camera roll, the pictures that have been taken with the iPhone's camera. Those pictures are also available in the Photos application, along with any transferred from iPhoto or Aperture on a Mac, or Photoshop in Windows.

Internet connectivity

web browser in landscape mode Internet access is available when the iPhone is connected to a local area Wi-Fi or a wide area GSM or EDGE network, both second-generation (2G) wireless data standards. The iPhone 3G introduced support for third-generation UMTS and HSDPA 3.6, By default, the iPhone will ask to join newly discovered Wi-Fi networks and prompt for the password when required. Alternatively, it can join closed Wi-Fi networks manually. Wi-Fi, Bluetooth, and 3G (on the iPhone 3G and 3GS) can all be deactivated individually. Airplane mode disables all wireless connections at once, overriding other preferences. However, once in Airplane mode, one can explicitly enable Wi-Fi and/or Bluetooth modes to join and continue to operate over one or both of those networks while the cellular network transceivers remain off. The iPhone 3GS has a maximum download rate of 7.2�Mbit/s. Safari is the iPhone's native web browser, and it displays pages similar to its Mac and Windows counterparts. Web pages may be viewed in portrait or landscape mode and supports automatic zooming by pinching together or spreading apart fingertips on the screen, or by double-tapping text or images. The maps application can access Google Maps in map, satellite, or hybrid form. It can also generate directions between two locations, while providing optional real-time traffic information. During the iPhone's announcement, Jobs demonstrated this feature by searching for nearby Starbucks locations and then placing a prank call to one with a single tap. Apple also developed a separate application to view YouTube videos on the iPhone, which streams videos after encoding them using the H.264 codec. Simple weather and stock quotes applications also tap in to the Internet. iPhone users can and do access the Internet frequently, and in a variety of places. According to Google, the iPhone generates 50 times more search requests than any other mobile handset.

Text input

on the original iPhone's touchscreen. For text input, the iPhone 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 keyboard can predict what word the user is typing and complete it, and correct for the accidental pressing of keys near the presumed desired key. The 3.0 update brought support for cut, copy, or pasting text, as well as landscape keyboards in more applications.

E-mail and text messages

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, Word, Excel, and Powerpoint attachments to mail messages can be viewed on the phone. 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 currently has built-in support for e-mail message forwarding, drafts, and direct internal camera-to-e-mail picture sending. Support for multi-recipient SMS was added in the 1.1.3 software update.

Third party applications

:''See also: iPhone SDK and App Store'' At WWDC 2007 on June 11, 2007 Apple announced that the iPhone would support third-party "web applications" written in Ajax that share the look and feel of the iPhone interface. Once a developer has submitted an application to the App Store, Apple holds firm control over its distribution. For example, Apple can halt the distribution of applications it deems inappropriate as has happened with a US$1000 program that has as sole purpose to demonstrate the wealth of its user. Before the SDK was released, third-parties were permitted to design "Web Apps" that would run through Safari.

Accessibility

The iPhone can enlarge text to make it more accessible for vision-impaired users,

Intellectual property

Apple has filed more than 200 patent applications related to the technology behind the iPhone. LG Electronics claimed the iPhone's design was copied from the LG Prada. Woo-Young Kwak, head of LG Mobile Handset R&D Center, said at a press conference, “We consider that Apple copied Prada phone after the design was unveiled when it was presented in the iF Design Award and won the prize in September 2006.” On September 3, 1993, Infogear filed for the U.S. trademark "I PHONE" In October 2002, Apple applied for the "iPhone" trademark in the United Kingdom, Australia, Singapore, and the European Union. A Canadian application followed in October 2004 and a New Zealand application in September 2006. As of October 2006 only the Singapore and Australian applications had been granted. In September 2006, a company called Ocean Telecom Services applied for an "iPhone" trademark in the United States, United Kingdom and Hong Kong, following a filing in Trinidad and Tobago. The Canadian application was opposed in August 2005 by a Canadian company called Comwave who themselves applied for the trademark three months later. Comwave has been selling VoIP devices called iPhone since 2004. Shortly after Steve Jobs' January 9, 2007 announcement that Apple would be selling a product called iPhone in June 2007, Cisco issued a statement that it had been negotiating trademark licensing with Apple and expected Apple to agree to the final documents that had been submitted the night before. On February 2, 2007, Apple and Cisco announced that they had agreed to temporarily suspend litigation while they held settlement talks, The iPhone has also inspired several leading high-tech clones, On October 22, 2009 Nokia filed a lawsuit against Apple for infringement of its GSM, UMTS and WLAN patents. Nokia alleges that Apple has been violating ten of Nokia's patents since the iPhone's initial release.

Restrictions

Apple tightly controls certain aspects of the iPhone. The hacker community has found many workarounds, most of which are condemned by Apple and threaten to void the device's warranty.

Activation

The iPhone normally prevents access to its media player and web features unless it has also been activated as a phone with an authorized carrier. On July 3, 2007, Jon Lech Johansen reported on his blog that he had successfully bypassed this requirement and unlocked the iPhone's other features with a combination of custom software and modification of the iTunes binary. He published the software and offsets for others to use. Unlike the original, the iPhone 3G must be activated in the store in most countries. Apple avoided this by releasing the 3.0 software two days before the iPhone 3GS. Users on the O2 network in the United Kingdom, however, can buy the phone online and activate it via iTunes as with the previous model.

Unlicensed third party software and jailbreaking

The iPhone's operating system is designed to only run software that has an Apple-approved cryptographic signature. This restriction can be overcome by "jailbreaking" the phone,

SIM unlocking

=

United States

= tray partially ejected. Most iPhones are sold with a SIM lock, which restricts the use of the phone to one particular carrier, a common practice with subsidized GSM phones. Unlike most GSM phones however, the phone cannot be officially unlocked by entering a code. The locked/unlocked state is maintained on Apple's servers per IMEI and is set when the iPhone is activated. While the iPhone was initially sold in the US only on the AT&T network with a SIM lock in place, various hackers have found methods to "unlock" the phone from a specific network. AT&T has stated that the "iPhone cannot be unlocked, even if you are out of contract". Unable to offer the iPhones to customers, AT&T competitors such as Verizon Wireless offer other smart phones, many running the Android (operating system). Outside of the United States, policies differ. =

United Kingdom

= O2, Orange, 3, Vodafone and T-Mobile in the United Kingdom are allowed to sell it, with MVNO (mobile virtual network operator) Tesco Mobile also offering deals, thus the only operator not selling the iPhone currently is MVNO Virgin Mobile. The new iPhone 4 in the UK is also sold unlocked without a contract for full retail price, for use on any network the user chooses, but only when bought at the physical Apple Stores or the Apple Online Store. =

Australia

= Four major carriers in Australia, (Three, Optus, Telstra, and Vodafone), offer legitimate unlocking. =

Denmark

= In Denmark it is unlocked after 6 months of contract have passed, or earlier if you pay DKK 500 (approx. €70) for unlocking. =

Other countries

= It is also available without any SIM lock for full retail price in some countries. These include South Africa, Singapore, Greece, Taiwan, China, Hong Kong, Italy, New Zealand and Russia, vendors sell iPhones not locked to any carrier.
