Apple has released the iOS 7 to the public on Wednesday, and here is how to download it and install on the supported devices.

Apple (NASDAQ:AAPL), as expected earlier, released its new iOS 7 mobile operating system for the iPhone, iPad, iPad mini and the iPod touch on Wednesday, and according to reports, the redesigned version of the platform has improved significantly since the first beta was released in June.

Apple rolled out the iOS 7 as an over-the-air update, which requires users to go to Settings > General > Software Update on their devices to perform the update using a Wi-Fi connection. Users can also update their device to iOS 7 by connecting it to a computer via a USB cable -- a process that will require iTunes 11.1 (Download), which is the latest version of the iTunes software.

However, as Apple’s servers might be facing overload issues, users are recommended to directly download the specific iPhone software, or IPSW, file for their respective device and use that to install the iOS 7. The iOS 7 direct download links can be found at the bottom of this article.

How To Install iOS 7

Step 1: Before installation, users should perform a backup of their device. Connect the device to the computer via USB and launch iTunes 11.1 on your computer. After that, choose your device in the upper right corner of the iTunes window.

Step 2: After choosing your device’s name, go to the Summary tab and check “This computer” option under “Backups.” Once you do that, click on the “Back Up Now” button.

Step 3: Now go to the Updates tab in the iTunes Apps section to update your iOS app. You can also copy the device backup files to an external drive or PC. To see where iTunes stored the device backup files on your computer, select “Preferences” from the iTunes menu and navigate to the “Devices” tab.

Step 4: If you have not downloaded the IPSW file for your device, you can click on the “Check for Update” button. But, if you have the specific IPSW file saved on your desktop, hold Alt and click on the “Restore iPhone” button in iTunes.

Step 5: After a small window pops up, navigate to the IPSW file on your desktop, select it and click on Open.

Step 6: Click on “Restore” on a subsequent pop-up window and it will initiate the restoring process, which will take some time to finish.

Step 7: After it is done, you will see a completion screen. The rest of the process will be continued on the device.
