Due to the old iPhone 4 model, iOS 8 is not supported at present. The system can be upgraded up to a version. But after upgrading to this version, the phone will be very stuck, so I personally recommend that your iphone4 be upgraded to the highest level, so that the user experience will be better.

6 (Preview).

7iOS 7 brings a new look to this operating system, which is already a bit old. In addition to the youthful color scheme and UI, there are also a lot of changes in this system.

Appearance. iOS 7 is being developed under the leadership of Jony Ive. He boldly eschewed the style of the Steve Jobs era and brought a major visual change to the system.

The skeuomorphism, textures, and glittering icons are all gone, and the overall style of iOS 7 is more modern and flat.

Control Center. Another example borrowed from Android. Users no longer have to go into the settings app to adjust the device's functions, and now they can simply swipe up from the bottom of the screen to pull out the control center with many quick switches, such as volume and brightness adjustments, Wi-Fi and Bluetooth Do Not Disturb switches.

itunes radio。This ** streaming service is Apple's attempt to challenge Spotify and Rdio. It allows users to choose songs based on their needs, but the service is more about stations, stations, and genres around songs, artists, and genres.

Camera and **. The new camera app is no longer the "point-and-shoot" app it used to be, and users can adjust some of the shooting parameters while using the built-in filters. The app also adds a sorting function of events or locations, allowing users to organize their own photos more intuitively.

Multitasking. This feature has been greatly upgraded in iOS 7. Double-tapping the home button will open a new multitasking interface that will show the icon and thumbnail of each open app, and the way to close the app is even easier than swiping up by tapping on the app's thumbnail.

Recommend upgrading, why that? Because it is currently very stuck, it takes more than 10 seconds to type out, and it is also stuck to play games, and it is definitely not possible to upgrade, so why should it be recommended to upgrade that first?

Because Apple will release the latest official version of the firmware on March 15, proving to solve the problems of high version cards, slowness, etc., the beta version has been tested very well, and the mobile phone runs fast.

The following methods are recommended.

Turn on the one-click flash to the latest version.

On March 15th, it was updated to the official version again with AISI.

Not good, it is not recommended to upgrade ios7 card to death, and you can't downgrade after upgrading.

There's nothing wrong with that, but speed comes at a cost.

iOS 6 has not been jailbroken successfully for the time being, and now it can only be jailbroken iOS

4 After upgrading, you can downgrade, please don't mislead the landlord if you don't understand!
