Can you install iOS 8 on iPhone 4?

If you have an iPhone 4 and are keen to enjoy the latest version of the smartphone's operating system, iOS 8, you should know that you won't be able to. The oldest model that accepts this system update is the iPhone 4s. Still, it is not recommended that you install it, as many users have reported that their iPhone 4s runs much slower with the update installed. At OneHowTo.com we answer the question of whether iOS8 can be installed on iPhone 4.

Steps to follow:


As we said, you cannot install iOS8 on the iPhone 4 unless your phone is jailbroken (step 7), so if you want to enjoy all the new updates, you will have to think about renewing your phone. If you worry about the expense involved, consider the possibility of selling your iPhone so you will get some money for the new smartphone.


The oldest iPhone model that accepts the latest iOS update is the iPhone 4s. However, although you can download it, it isn't advisable if you want to keep a mobile phone that works with agility and quickly responds to your demands, without crashing.

These are the models that accept iOS 8:

  • iPhone 4S.
  • iPhone5.
  • iPhone 5S.
  • iPhone 5C.
  • iPhone 6.
  • iPhone 6 Plus.

The usual thing that happens, and many users have confirmed so in this particular case, is that when an older iPhone model downloads the latest version of the operating system, designed for the newest iPhone model - 6 and 6 Plus today-operation is not as optimal and begins to go slowly.


Whether for purely technical reasons or for marketing and trade reasons, the fact is that this is so even on an iPhone 5, iOS 8 does not work perfectly and a slight drop in performance is noticed.


In any case, if you want to upgrade to the latest version of iOS that your model of the iPhone accepts, you have go to "Settings" then to "General" and then to "Software Update". If there is a new version for your phone, you will be prompted to download it; if, however, this is not the case, a message will appear indicating that the software is up to date.


In the event that you update and an error appears, we recommend visiting this Apple page in which they explain the meaning of fault codes from their systems: http://support.apple.com/kb/TS3694? viewlocale = en_US.


If you want to install iOS 8 on your iPhone 4 with a jailbreak, you'll need to install it on your iPhone 4, though, as we said before, it's not recommended.


Once you have jailbroken your iPhone, you'll be able to access Cydia on your phone. Search for the cydia tweaks for iOS 7 users which are the following:

  • Interactive Message Notifications
  • Activator
  • Notific8
  • Winterboard
  • PredictiveKeyboard
  • MessageRenamer7
  • IntelliscreenX7
  • Centrex (iOS 8 Control Center)

You'll only need to install them to get your iPhone4 updated. We remind you that this is not a recommended option.

Hi Bijay,

To downgrade from iOS 8 to iOS 7.1.2 you will have to install a special firmware file which allows you to do this through your iTunes. However, Apple doesn't like you to do this, so finding the firmware can be difficult and might also take you to disreputable sites which have malware instead. Also, downgrading doe snot back up your files and you won't be able to get them back if you haven't done so.

Hi there,
As we mention in the article, the only way to do so is by jailbreaking your iPhone 4, as the system won't let you install it by default.
Hope this helps

How do I do that?
I wish that you could. I dont even want all of the features of the ios 8. I just want to be able to find a way to get the update for the messages without having to buy another new phone. It takes so long and I want to be able to just reply by swiping down or by responding on the home screen without having to go through the trouble of unlocking it then waiting for my messages to load so I can read them then reply... If anyone has any ideas please get back to me ASAP!!!
