What You Can Install On Iphone 4

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

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

You can find out which iOS and which iPhone you can install in this article.

iPhone 3GS

Minimum iOS Version: iOS 4.1 (8B117)
IOS max version: iOS 6.1.6 (10B500)
Average update size: 382. 784 MB

With the “high-speed” version of the iPhone 3GS, Apple did very generously. The latest firmware version is iOS 6.1.6. But with the version of iOS 5 we got a strange situation. She no longer subscribes and it is impossible to establish it. At the same time, the minimum possible iOS that will work on the smartphone is iOS 4.1.

iPhone 4 (GSM / CDMA)

Minimum iOS Version: iOS 7.1.2 (build depends on model)
IOS max version: iOS 7.1.2 (build depends on 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 has closed any options. A complete rejection of skeuomorphism by the company was met by a forced transition to a “flat” iOS 7. Be careful when installing, since iPhone 4 is presented in three versions: GSM, CDMA, and GSM (rev. A) 2012. Each must have its own firmware.

iPhone 4s

Minimum iOS Version: iOS 9.3.5 (13G36)
IOS max version: iOS 9.3.5 (13G36)
Average update size: 1.5 GB

Until September 2016, 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)
IOS max version: updates are relevant

The first smartphone Apple has opened access to the latest iOS 10 firmware. Together with the iPhone 5, the current version of iOS 10 can 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.
