The much anticipated wait for iOS 7 has finally ended this afternoon when Apple pushed out the finished version to non-developers via iTunes and iOS. The download requires 3.1GB of space on your iPhone so if you like to thread the needle with your iPhone’s available space, you’ll probably need to rid yourself of some unused apps or unnecessary media files in order to make the upgrade. In case you need a refresher on what’s new in iOS 7, you can get an in-depth rundown from our previous article: iOS 7 Overview & Details.
It is also important to note that you may run into issues trying to download and install the new firmware. I had this happen to me and it took around 25 failed attempts before I was able to successfully download and install iOS 7 onto my iPhone 5. The reason for this is likely due to the massive influx of people who are trying to download and install the update all at once. This is causing the system to overflow thus giving many users errors. I’d expect these issues to settle out over the next few hours and potentially the next few days as more and more users finish the upgrade to iOS 7. Good luck with your updating process and enjoy iOS 7!
