How to install iOS 7
Apple announced iPhone 5s and iPhone 5c event that iOS 7 will be released on September 18.
However, it looks like just like the previous beta versions it is possible for without having their iOS device’s UDID registered with a developer account to install iOS 7 golden master (GM) that was seeded yesterday.
So if you can’t wait until next week then here are the simple steps to install iOS 7 on your device right now courtesy folks at LifeHacker who have posted the download links for iOS 7 GM as well.
Here are some important points before you proceed:
- Even though its iOS 7 GM, the public release is likely to be the same build number, and the risks associated with installing the beta version are reduced, please proceed with caution.
- Apple could clamp down on this and prevent non-developers from using iOS 7 GM.
- Since the build number of iOS 7 GM and the final iOS 7 version will be the same, you won’t get an OTA update to install the final version of iOS 7 when it is released next week. You will have to follow the same process to install it when iOS 7 is released next week.
