iPhone 4s Language

At announcement plans were in place for the iPhone 4S to support many languages from around the world. 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. Since it uses a software based keyboard supported by the multi-touch display, it can support many different keyboard layouts without having to change physically. The iPhone 4S can display different languages and scripts at the same time.

Siri

The iPhone 4S introduced a new automated voice control system called "Siri", unique to the 4S^, that allows the user to give the iPhone commands, which it can execute and respond to. For example, iPhone commands such as "What is the weather going to be like?" will generate a response such as "The weather is to be cloudy and rainy and drop to 54 degrees today". These commands can vary greatly and control almost every section of the phone. 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 an extra amount of time (compared to using the regular function). An impact of Siri, as pointed out by Apple video messages, is that it is much easier and/or possible for people to use device functions while driving, exercising, or when they have their hands full. It also means people with trouble reading, seeing, or typing can access the phone more easily.

iPhone 4s Messaging

On the iPhone 4S, texting can be done aided by the voice assistant which allows speech-to-text. In addition to regular texting, messaging on the iPhone 4S is supported by iMessage, a specialized instant messaging program and service that allows unlimited texting to other Apple iOS 5 products. This supports the inclusion of media in text messages, integration with the device's voice controlled software assistant, and read receipts for sent messages. iMessages are in blue, and regular texts in green in the screen bubbles.

Since Siri can send text messages, a person can text and drive without taking their eyes off the road, as shown in Apple's video ad. Another example, is that a person can ask Siri for information while they are cooking and their hands are messy. It also makes it much easier for people with physical disabilities such as blindness to compose and send text messages.

iPhone 4s gaming system

The iPhone 4S uses the Apple A5 system-on-a-chip that uses an Imagination Technologies Power VR SGX graphics processing unit, which features pixel, vertex, and geometry shadier hardware, supporting OpenGL ES 2.0.. The SGX543 is an improved version of the GPU used in the iPhone 4S’ predecessor, the iPhone 4. However, the iPhone 4S uses a dual-core model, the SGX543, that is integrated with the Apple A5,which is in the same way as the iPad 2

Apple’s claim that the iPhone 4S can process graphics up to “seven times faster” than the iPhone 4 was corroborated by Epic Games President Mike Capps. At the “Let’s Talk iPhone” event held by Apple on October 4, 2011, Capps demonstrated Epic Games’ Infinity Blade 2, the sequel to Infinity Blade, on an iPhone 4S. Capps boasted that the game uses Epic Games’ Unreal Engine 3 and features the same graphic techniques used in the Xbox 360 game Gears.

Gaming on the iPhone 4S has been likened to the PlayStation Vita, that features the same SGX GPU only in a quad-core configuration, and the Nintendo 3DS handheld game consoles. Further, the iPhone 4S’ ability to process 30 million polygons per second has been compared to the PlayStation 3 and the Xbox 360 home video game consoles that can process 275 million and 500 million polygons per second respectively.

CVG’s deputy editor Andy Robinson told TechRadar that the “[iPhone 4S] is certainly laying down some serious credibility for the iPhone as a core gaming device. Not only is it now pushing out games that simply eclipse the [Nintendo 3DS] visually, but features like cloud saving and TV streaming support are really exciting for gamers.”

Senior Gaming Analyst at Jon Paddies Research Ted Pollack believes the biggest improvement to gaming on the iPhone 4S is the voice control features, noting that “one of the features that Nintendogs players loved was the ability to talk to it. 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.”

Comparison between iPhone 4 antenna and iPhone 4S antenna

Improving on the external stainless steel, dual-antenna design of its predecessor, the iPhone 4, Apple has redesigned the antenna in the iPhone 4S so that the cellular radio in the phone can alternate between two antennas, depending on which is sending/receiving the best signal. These two antennas form part of the stainless steel band that covers the sides of the iPhone 4 and 4S.

The bands on the iPhone 4 are divided into four antennas, cellular, Bluetooth, GPS, and Wi-Fi. In both the iPhone 4 and 4S, the cellular (GSM) antenna is divided into two. 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.

The iPhone 4S can support a maximum output theoretically of up to 14.4 Mbps with HSDPA as a result of an upgraded radio chip inside the phone, in addition to being a world phone, so both CDMA and GSM customers can roam internationally on GSM networks. It also supports Bluetooth 4.0.
