How to find out what ios is on iphone 4. How to find out the version of iOS installed on iPhone? Determining iPhone Model Using iTunes

iOS is the operating system that all mobile devices from the American company Apple are provided with. Any apple smartphone or tablet is sold with iOS pre-installed, so before buying a device, it is very important to make sure that the current version of the operating system is installed on it. This will make using the device more comfortable and avoid some problems.

How to check iOS version

Before answering the question of how to find out the version of iOS on an iPad or iPhone, it should be noted why exactly the owner of a mobile device needs to have such information. Knowing the iOS generation will help:

have a general understanding of the generation of the system, its functions and capabilities, including the ability to install and fully use various applications and games;
quickly and effectively solve problems arising with iOS, both independently and when communicating with the technical support service of the operating system;
have an idea about the possibility (opening access to the file structure of the OS).

How to see the version of iOS? To do this is quite simple using one of two methods:

How to find out your iOS using a computer

To find out the version of the system used on the iPad using this method, we need a computer with . You just need to connect the gadget to your computer, launch iTunes and wait for the iPad to sync with the program. Then click on the device and go to the "Overview" tab. Before us appears detailed information about the version of iOS installed on the tablet. Here you can also update the system if the existing operating system is outdated and has lost its relevance.

How to find out which iOS without a computer

In order to view the OS used on the device without connecting the device to a computer, just go to "Settings", go to the "General" subsection, and then "About this device". The information we need is displayed in the "Version" column. To update iOS to the latest one, you will need to go to the “Software Update” main settings item, but this should only be done with a stable Internet connection.

Now you know how to view the iOS version, which means you have useful information about your mobile gadget.

Smartphones and tablets from Apple have one feature, their body does not indicate the exact model name. Instead, it just says iPhone or iPad. It looks nice and stylish, but in some cases it is inconvenient because it is difficult to determine which model is in front of you. Now we will look at several ways to determine the iPhone model in this situation.

Identify iPhone model by model number

The easiest and most reliable way to find out which iPhone model you have is to look at the model number. Knowing the model number, you can easily determine the name of the model. This can be done using the table on this page, or you can simply enter the model number into any search engine and examine the results.

The model number is always listed at the bottom of the iPhone's back cover and is represented as "Model A1429", where "A1429" is actually the model number. The picture below shows what it looks like on an iPhone 6s.

Below is a table with a list of all currently existing iPhone models and the numbers that correspond to them.

Identify iPhone model by serial number

You can also find out the iPhone model by its serial number. Unlike iPads, the serial number is not indicated on the iPhone case, so to find out you need to open Settings and go to the “General - About this device” section.

Once you have the serial number, you can go to Apple's Service and Support Entitlement page to find the model that matches that serial number. To do this, go to , enter the serial number, verification code and click "Continue".

If everything is done correctly, a page will load where you can find out the model of your iPhone.

Determining iPhone Model Using iTunes

Another way to find out the iPhone model is iTunes. To use this method, connect your iPhone to your computer and launch iTunes. The icon of the connected device will appear in the upper left corner of the iTunes window, click it to go to the iPhone settings.

As a result, a page will appear on which you can find out the iPhone model, the capacity of its built-in memory, serial number and other similar information.

iOS is the mobile operating system for iPhone and iPad. Many users know the model of their smartphone or tablet, but do not know what version of iOS they have. Knowing your version of iOS is essential for app compatibility, feature availability, and more.

Here's how to check the current version of iOS on your iPhone, iPad, or iPod touch.

How to find out the versioniOS on theiPhone oriPad

Open the app Settings on your iPhone or iPad.
Go to Main.
Select About this device.
Find the line Version, and next to it will be the version of iOS installed on your iPhone or iPad.

Along with the iOS version number, you will also see the build number.

The method will be the same for iPhone, iPad and iPod touch, regardless of which version of the system you have installed.

Regular users may not care what version of iOS they have, but this knowledge can help you troubleshoot system issues, check app compatibility, and know what features are available to you. In addition, the system version must be known in order to use IPSW files.

If you do not have the latest version of the system installed, you can update the device through Settings > General > Software update. Be sure to back up your device before doing this.

You can also find out the version of iOS on your iPhone or iPad by connecting them to your computer and launching iTunes. The system version will be on the device information tab.

With the release of updates to the mobile operating system iOS, Apple is much more organized than the competing product from Google. And although the number of smartphone models that support iOS hardly reaches two dozen, from time to time the company restricts access to the current firmware version on devices that it considers “obsolete”.

This is due both to hardware incompatibility and device performance (for example, it is extremely difficult to imagine the iPhone 3GS working on iOS 10), and to a marketing decision. After all, Apple stops signing past firmware and restricts access to new ones. You cannot install unsigned firmware (firmware with an expired digital certificate).

Which iOS and which iPhone can be installed - you will learn in this material.

iPhone 2G

Minimum iOS Version: iPhone OS 1.0 (1A543a)
Maximum iOS Version: iOS 3.1.3 (7E18)
Average update size: 91 - 245 MB

The original iPhone was the only device on which you can install the first version of the operating system. Then they were called like iPhone OS. The latest firmware available for installation on the original iPhone is iOS 3.1.3. Downgrade is available.

iPhone3G

Minimum iOS Version: iOS 2.0 (5A347)
Maximum iOS Version: iOS 4.2.1 (8C148)
Average update size: 225 - 322 MB

The updated iPhone 3G came out of the box with iOS 2.0. The firmware is supported to this day. Upgrading above iOS 4.2.1 is not possible. Please note that Apple does not sign iOS 4.0, 4.0.1 and 4.0.2 firmware.

iPhone 3GS

Minimum iOS Version: iOS 4.1 (8B117)
Maximum iOS Version: iOS 6.1.6 (10B500)
Average update size: 382 - 784 MB

With the "high-speed" version of the iPhone 3GS, Apple acted very generously. The latest firmware version is iOS 6.1.6. But with the version of iOS 5, a strange situation turned out. It is no longer signed and cannot be installed. At the same time, the minimum possible iOS that will work on a smartphone is iOS 4.1.

iPhone 4 (GSM/CDMA)

Minimum iOS Version
Maximum iOS Version: iOS 7.1.2 (build depends on the model)
Average update size: 1.12 GB

The only firmware that can be installed on the iPhone 4 is iOS 7.1.2. Starting with the iPhone 4, Apple closed any selection options. A complete rejection of skeuomorphism on the part of the company was met with a forced transition to “flat” iOS 7. Be careful during installation, since the iPhone 4 is presented in three versions: GSM, CDMA and GSM (rev. A) 2012. You need to install your own firmware for each.

iPhone 4s

Minimum iOS Version: iOS 9.3.5 (13G36)
Maximum iOS Version: iOS 9.3.5 (13G36)
Average update size: 1.5 GB

Until September 2016, the iPhone 4s supported the current iOS 9 firmware. With the release of iOS 10, Apple limited the installation of new items for a smartphone released 4 years ago.

iPhone 5 and all subsequent models released after 2012

Minimum iOS Version: iOS 10.0.2 (14A456)
Maximum iOS Version: updates are up to date

The first smartphone to which Apple opened access to the latest iOS 10 firmware. Together with the iPhone 5, the current version of iOS 10 can also be installed on:

iPhone 5s, 5c
iPhone 6, 6 Plus
iPhone SE
iPhone 6s, 6s Plus
iPhone 7, 7 Plus.

At the time of publication of this material, the current version of iOS 10 remains iOS 10.1. iOS firmware version 10.0.1 cannot be installed because Apple has stopped signing it.

You can download the latest versions of iOS for a specific device on the IPSW.me website. There you can also find out the status of the system subscription from Apple.

Today we will talk about the heart of the iPhone and I will tell you what iOS is. Oddly enough, some people don't know the name of the operating system on the iPhone.

There is nothing wrong with that, because now you are here and you can read this material. I will try to summarize the information that I have.

iOS system - what is it?

Well, I’ll probably start with the fact that as soon as the first iPhone was released in 2007, there was no name for the operating system yet. Given that it was based on an OS identical to the MacBook, it was called OS X.

I won’t talk about the name for a long time, because it’s already clear that Apple’s trick is simply to add the letter “i” to everything at the beginning. So iOS turned out, well, I think it's no secret to anyone that OS is Operating System.

Although it is quite possible that it stands for completely "iPhone Operating System". Apple gives its users the opportunity to think for themselves.

It works not only on the iPhone. It was designed for mainstream mobile devices and you can add iPad and iPod.

The entire operation of the system is based on the touch screen. There are no styluses, only fingers. An exception not so long ago was the iPad Pro, but there is something like a pen and it is needed exclusively for drawing.

The main feature can be noted that the system is completely closed. You will not be able to download any file to the device. To do this, you will have to do various manipulations and download a special application.

If we talk about applications and games, then they can be downloaded from the App Store. There are a lot of them now and you can find absolutely everything you need.

How to find out which iOS is on iPhone?

If you are interested in seeing your version of iOS on iPhone, then you can do it in just a couple of seconds. Just follow these steps:

choose Settings;
then click on Main;
now About this device;
opposite the word "Version" we have the number of the current iOS.

With these simple steps, you can find out the version at any time you need. The first time according to the instructions, and then I think you will remember.

How is iOS different from Android?

I won’t talk too much here, I’ll just tell you the most important differences between iOS and Android and how things are in general at the moment.

The first thing I would like to point out is that safety. After all, Android devices are most often hacked, placing a virus there is not such a problem.

There are probably several reasons for this. The first is that the Play Market checks applications a little worse and you can take into account that people like to install hacked software.

Well, the second is that Android is completely open. Everyone has studied it inside and out. So everyone knows her strengths and weaknesses.

The second difference can be ecosystem. After all, now before choosing a device, you must understand what services you want to use.

Android has all the analogues for Apple services. Speaking of iCloud, we immediately recall Google Drive. If it's Siri, then OK Google, and so on.

Both sides have their pros and cons. But this is an individual matter and it is best for you to consult with users or just read information on the Internet.

Next, you can call work stability and device support. In principle, today the difference is not as big as it used to be.

If you take an Android smartphone in your hands three years ago and use it, then you can certainly find a bunch of lags and slowdowns that are incredibly annoying.

Today, of course, this is also sometimes observed, but much less frequently. More concerned is that when you buy a device on this OS, how long will it be updated to the latest versions.

With Apple, this period is usually about four years. While Android is a couple of years old and you can forget about the latest versions.

It is worth considering the fact that each developer has his own shell. Because of this, it is not certain that you will be able to receive updates as soon as a new version of Android is released.
