While there have been a number of iOS threats throughout the years, they mostly targeted jailbroken devices. In the case of Masque and WireLurker, even non-jailbroken devices are put at risk. The way that the iOS environment is built is quite similar to a walled garden, where devices are only allowed to download digitally signed apps from the official Apple app store. This may not work for big companies that need to develop and rapidly deploy apps to their employees.
In the case of WireLurker , a mobile app developer lost control of their signing certificate, which was used to allow malicious apps to be signed and therefore, trusted. Here are the times when iOS threats showed that a closed ecosystem for apps may not ensure total app security:.
Apart from iOS threats, we have also previously reported a few notable and notorious threats that target the Mac OS. These and the iOS threats combined show the growing interest of cybercriminals in Apple users. Owing to the fact that the company attracts a certain group of high-paying customers for premium products, tapping into this market can be quite lucrative. While the total count for Android threats reach millions, threats to Apple products may appear too few to even worry about.
However, ultimately, it is this mindset of complacency that often leads to drastic consequences. Users still have to be proactive against threats no matter what the platform. Like it? Add this infographic to your site: Click on the box below.
Further worldwide rollout, including 22 additional countries on October 28, came over the next several months. Retaining most of the external design of the iPhone 4, the 4S hosted major internal upgrades, including an upgrade to the Apple A5 chipset, and an 8-megapixel camera with p video recording. Reception to the iPhone 4S was generally favorable. Reviewers noted Siri, the new camera, and processing speeds as significant advantages over the prior model. The 4S was officially discontinued on September 9, following the announcement of the iPhone 6, although production did continue for developing markets until February 17, During the course of its lifetime, the iPhone 4S was the best-selling iPhone ever produced and it is the first iPhone to support five major versions of iOS: The 4S is also the last iPhone to have the original 30 pin connector as the succeeding iPhone 5 replaced it with the all digital Lightning Connector.
Contents1 Origin2 Features2. It was also Cook's first launch without Apple co-founder Steve Jobs, whose health was deteriorating, and he died the day after the announcement of the iPhone 4S. Tim Carmody of Wired praised Cook for focusing on company achievements, calling him a 'global business thinker' and a 'taskmaster'.
Capps boasted that the game uses Epic Games' Unreal Engine 3 and features the same graphic techniques used in the Xbox game Gears of War 3. This was unusual for Apple as an upper case 'S' had been used since the introduction of the iPhone 3GS in It is the first iPhone that does not need to connect to iTunes in order to be activated because iOS 5 introduces features like iCloud. Interface control elements consist of sliders, switches, and buttons.
The response to user input is immediate and provides a fluid interface. Internal accelerometers are used by some applications to respond to shaking the device one common result is the undo command or rotating it in three dimensions one common result is switching from portrait to landscape mode. The iPhone 4S can play music, movies, television shows, ebooks, audiobooks, and podcasts and 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. 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 4S, 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. For example, iPhone commands such as 'What is the weather going to be like?
The commands given do not have to be specific and can be used with natural language. Siri can be accessed by holding down the home button for a short amount of time compared to using the regular function.
An impact of Siri, as shown by Apple video messages, is that it is much easier for people to use device functions while driving, exercising, or when they have their hands full. This supports the inclusion of media in text messages, integration with the device's voice controlled software assistant, and read receipts for sent messages. Input to the computer comes from a keyboard displayed on the multi-touch screen or by voice-to text by speaking into the microphone. Entered text is supported by predictive and suggestion software as well as a spell-checker, that includes many regional dialects like Swiss spoken French.
Different features have different language requirements, such as keyboards compared to the word predictor and spell-checker, which needs a large dictionary of words. Language support is related to the iOS 5 operating system that the device launched with, although not always. The Siri digital assistant supported French, English, and German at launch.
The iPhone 4S can display different languages and scripts at the same time. Although the device has improved performance over iOS 7, some newer features that were released to newer models such as AirDrop and CarPlay were not supported. Given that the device was supported for more than 3 years, some newer features of the software such as Apple Pay were not supported.
It is also unable to work with Apple Watch due to the relatively aged hardware. In fact, some users often reported that performance on the 4S is very slow, similar to how iOS 7 ran on the iPhone 4, and suggesting that they should not upgrade due to battery draining issues and hanging up on calls. Meanwhile, Apple released iOS 8. This makes it the first iPhone to support 5 major versions of iOS, and the second iOS device to support 5 major versions iOS 9 will support the iPad 2 as well, bringing its total up to six major versions of iOS supported. Although the iPhone 4S has begun its limitations with iOS 8, iOS 9 is said to bring performance enhancements that may help the aging device run more smoothly again.
Hardware The iPhone 4S features a Sony 8-megapixel camera and p video recording. The screen is the same as the prior generation iPhones; 3. The new antenna is divided up into two pieces within the stainless steel band that wraps around the sides of the phone. Therefore, if the iPhone 4S is gripped in such a way as to attenuate one piece of the cellular antenna, the radio will switch to the other piece that isn't being gripped.
Other features of the camera are macro for close up pictures and faster capture including being able to take its first picture in 1. This is included on the black model as well but is less visible. The bottom of the device features a speaker output on the right and a microphone input on the left with Apple's proprietary pin dock connector in the center.
These include a three-axis gyroscope, an accelerometer, a proximity sensor, and an ambient light sensor. Notice the repositioning of the antennae which form the perimeter around the phone; the iPhone 4 antenna is on the top of the phone while on the iPhone 4S, the antennas are on the sides.
This side antenna placement meant a benefit of cellular signal attenuation and was used in later models like the iPhone 5. Apple redesigned the antenna in the iPhone 4 CDMA after some original iPhone 4 users reported cellular signal attenuation problems as a result of holding the phone in certain positions. These two antennas are incorporated into the distinctive stainless steel band that wraps around the sides of the iPhone 4S. The '4' generation iPhones differ from earlier Apple designs; the bulges of the back panel as well as the band between the front and back are gone and have been replaced with flattened surfaces.
The redesign reflects the utilitarianism and uniformity of existing Apple products, such as the iPad and the iMac. The overall dimensions of the iPhone 4S are lower than that of the 3GS. The internal components are situated between two panels of aluminosilicate glass, described by Apple as being 'chemically strengthened to be 20 times stiffer and 30 times harder than plastic,' theoretically allowing it to be more scratch-resistant and durable than the prior models.
Brian Chen of Wired said that 'the fifth-generation iPhone's superb camera and speedy dual-core processor are classy additions.

But Siri is the reason people should buy this phone. Lu of Gartner believed that Apple no longer had the leading edge and that the 4S would only sell due to brand loyalty, as fans had been expecting an iPhone 5 with a thinner profile, edge-to-edge screen, and stronger features. Further, the iPhone 4S' ability to process 80 million polygons per second has been compared to the PlayStation 3 and the Xbox home video game consoles that can process million and million polygons per second respectively. Not only is it now pushing out games that simply eclipse the 3DS visually, but features like cloud saving and TV streaming support are really exciting for gamers.
There's no reason why a game like that couldn't be done on the iPhone 4S, and much more sophisticated given the voice control shown. The iPhone 4S together with the iPhone 4 has been notoriously been easily to crack its glass covers after an accidental fall. The design Glass body with stainless steel frame was later recycled in the future with the introduction of iPhone X.

Shot using an iPhone 6s. No audio on outgoing calls. This error may be due to a malfunctioning switch sensing the headphone plug and different handling of this information by different apps. Yellow-tinted screens primarily affecting white-cased units. Battery problems. As of February [update], Apple was still investigating the battery drain issue. Not understanding the accent of users from various countries while speaking to Siri. Previous iPhone models were released during or after declining sales figures. In addition, iPhone 4 users had high marks for being satisfied with their phone.
The German phone company Deutsche Telekom said they were 'satisfied' with consumer interest. Phil Schiller, Apple's senior vice president of Worldwide Product Marketing, stated that the 'iPhone 4S is off to a great start with more than four million sold in its first weekend—the most ever for a phone and more than double the iPhone 4 launch during its first three days. Apple also buys back previous generation iPhones under a special program.
