iPhone




The iPhone is a line of smartphones designed and marketed by Apple Inc. The iPhone runs Apple's iOS mobile operating system, originally named iPhone OS. The first iPhone was released in 2007; the most recent iPhone, the 6th-generation iPhone 5, was released on September 21, 2012. The user interface is built around the device's multi-touch screen, including a virtual keyboard rather than a physical one. The iPhone has Wi-Fi and cellular connectivity (2G, 3G and 4G (iPhone 5 only)).

An iPhone can shoot video (though this was not a standard feature until the iPhone 3GS), take photos, play music, send and receive email, browse the web, send texts, and receive visual voicemail. Other functions — games, reference, GPS navigation, social networking, etc. — can be enabled by downloading apps; as of 2012, the App Store offered more than 700,000 apps by Apple and third parties.

iOS 6 Features





Beautifully designed from the ground up (and the sky down), Maps changes the way you see the world. Map elements are vector based, so graphics and text are incredibly detailed — even when you zoom all the way in — and panning is smooth. Tilt and rotate to view an area, and Maps keeps the names of streets and places where they belong. Get visual and spoken turn-by-turn navigation and real-time traffic updates. Even soar over cityscapes to see the sights from the air in amazing, high-resolution quality.

IOS 6




HISTORY

iOS 6 was previewed on June 11, 2012 during WWDC 2012, with release announced for Fall 2012. Following the pattern of previous iOS releases, older devices are no longer supported, specifically the iPod Touch (3rd generation) and the iPad (original). Supported devices on this release include the iPhone 3GS onwards, the iPod Touch (4th generation) onwards, and the iPad 2 onwards.

IOS (Iphone Operating System)




iOS (previously iPhone OS) is a mobile operating system developed and distributed by Apple Inc. Originally released in 2007 for the iPhone and iPod Touch, it has been extended to support other Apple devices such as the iPad and Apple TV. Unlike Microsoft's Windows CE (Windows Phone) and Google's Android, Apple does not license iOS for installation on non-Apple hardware. As of September 12, 2012, Apple's App Store contained more than 700,000 iOS applications, which have collectively been downloaded more than 30 billion times. It had a 23% share of the smartphone operating system units sold in the first quarter of 2012, behind only Google's Android. In June 2012, it accounted for 65% of mobile web data consumption (including use on both the iPod Touch and the iPad). At the half of 2012, there were 410 million devices activated. According to the special media event held by Apple on September 12, 2012, 400 million devices have been sold through June 2012.

Bluetooth V4.0



The Bluetooth SIG completed the Bluetooth Core Specification version 4.0, which includes Classic Bluetooth, Bluetooth high speed and Bluetooth low energy protocols. Bluetooth high speed is based on Wi-Fi, and Classic Bluetooth consists of legacy Bluetooth protocols. This version has been adopted as of June 30, 2010.

Bluetooth low energy (BLE), previously known as WiBree, is a subset to Bluetooth v4.0 with an entirely new protocol stack for rapid build-up of simple links. As an alternative to the Bluetooth standard protocols that were introduced in Bluetooth v1.0 to v3.0, it is aimed at very low power applications running off a coin cell. Chip designs allow for two types of implementation, dual-mode, single-mode and enhanced past versions. The provisional names Wibree and Bluetooth ULP (Ultra Low Power) were abandoned and the BLE name was used for a while. In late 2011, new logos “Bluetooth Smart Ready” for hosts and “Bluetooth Smart” for sensors were introduced as the general-public face of BLE.

  • In a single mode implementation the low energy protocol stack is implemented solely. CSR, Nordic Semiconductor and Texas Instruments have released single mode Bluetooth low energy solutions.
  • In a dual-mode implementation, Bluetooth low energy functionality is integrated into an existing Classic Bluetooth controller. Currently (2011-03) the following semiconductor companies have announced the availability of chips meeting the standard: Atheros, CSR, Broadcom and Texas Instruments. The compliant architecture shares all of Classic Bluetooth’s existing radio and functionality resulting in a negligible cost increase compared to Classic Bluetooth.


Cost-reduced single-mode chips, which enable highly integrated and compact devices, feature a lightweight Link Layer providing ultra-low power idle mode operation, simple device discovery, and reliable point-to-multipoint data transfer with advanced power-save and secure encrypted connections at the lowest possible cost.

General improvements in version 4.0 include the changes necessary to facilitate BLE modes, as well the Generic Attribute Profile (GATT) and Security Manager (SM) services with AES Encryption.

Core Specification Addendum 2 was unveiled in December 2011; it contains improvements to the audio Host Controller Interface and to the High Speed (802.11) Protocol Adaptation Layer.
