Updating an iphone to version 2 1
Owners of i Phone 4s and later, i Pad 2 and later, i Pod touch (5th generation) and later can get this update, according to Apple's support website. If a message asks to temporarily remove apps because i OS needs more space for the update, tap Continue or Cancel. VPN or proxy connections might prevent your device from contacting the i OS update servers.
You should be automatically notified that it's available, or you can update manually using i Tunes.. Update your device using i Tunes If you can't update wirelessly on your i OS device, you can update manually using i Tunes on a computer that you trust.
You can upgrade your phone or i Pod's firmware by selecting, "check for updates" in i Tunes.
As you can see at the bottom of this page, the oldest supported i Phone is the i Phone 4s. I have tried many times to install/update my i Phone 4 by computer, laptop, etc. Everything the user here describes is true in some way and for the language barrier and the fact the user is not exactly describing the problem you are downvoting. This answer doesn't correctly state the actual reason: because i OS after 7.1.2 specifically simply does not support the i Phone 4.
At today’s Apple event, the tech giant unveiled, among other things, a new operating system for the i Phone and i Pad. It’s not that much different from the previous OS, 9.2.1.
But even if you're sick of your phone prompting you to let it update every few hours, the changes within i OS 9.3 are definitely important. Most importantly, i OS 9.3 fixes a critical security bug in i Messages.
The testers cite reasons including not wanting new features to bog down their systems and wanting to keep their phones jailbroken, which we suppose makes sense.
Still, we like our i Phones working as quickly as possible, and it’s cool to see that this is actually happening between software versions.
But cybersecurity experts are urging consumers not to ignore this update, which fixes an unprecedented type of security flaw. Some i OS software updates aren't available wirelessly. You can also check your Settings app to see if there’s a small red alert badge, telling you it’s time to update.Even if you don't see the alert, you can manually force your device to update. https://en.wikipedia.org/wiki/i OS_8#Supported_devices The last supported OS is i OS 7.All of those tries did not work, because the other updates cannot be supported by the i Phone 4 for example; i Phone 4's screen is too small for the updates , some apps might have more GB which your i Phone 4 might have 32 GB or less which is not enough for the other apps in the update. It's not because of the screen size or storage, because a 16 GB i Phone 4S with the same screen can be upgraded to i OS 9.x.
