Apple’s iOS 7, the most dramatic visual overhaul of the company’s mobile operating system in its six year history, launches September 18 for the public. It will be available for all iPhones following the iPhone 4, the 5th generation iPod touch, and every iPad and iPad Mini except the original iPad.
To install iOS 7 on your iDevice, you can sign up for an Apple developer account, which costs you $100 per year and is the safest option. If you split it between a few friends, it can be very cheap. iOS 7 allows you to register up to 100 devices. Add your device’s UDID as a registered test device when you’ve signed up, and then go ahead and download the correct iOS 7 image for your device from the Apple developer portal. Once you have the image, skip to the installation section below. Also note that you need to back up your device using iTunes so that you can boot your iDevice into DFU mode and then restore the backup if anything goes wrong. When iOS 7 image is downloaded (if it’s a DMG file, you will need to open it up and extract the IPSW file), plug in your iDevice, and then open up iTunes. Once it’s connected, select the device you own and click on the Summary tab. Hold down the Option key (OS X) or the Shift key (Windows) and click the Restore button. Select the IPSW file from the dialog that pops up, and wait for the update to finish.
Be warned! If you have any need to sync your device, do not upgrade to iOS 7 until the new iTunes is released, or you have installed iTunes 11.1. Aiseesoft takes no responsibility for damaged or malfunctioning devices. Proceed at your own risk.
