If you are using the iOS 8 beta or iOS 8 GM you can upgrade to the full version of iOS 8 without downgrading to iOS 7, but you will need to manually upgrade to the iOS 8 release on your devices.
If you are still on the iOS 8 beta it’s a good idea to upgrade to the official iOS 8 release as soon as possible. For users trying the iOS 8 GM, there is less of a rush, but it is still a good idea to get back on to the latest official updates from Apple.
You can upgrade from the iOS 8 beta to the iOS 8 public release without any issues and you can even avoid a lengthy restore if you want to make the iOS 8 upgrade quickly.
You need a computer with iTunes, a charging cable and a little more time than a typical iOS 8 update to make this work. You cannot start this until the iOS 8 release time on September 17th, but you can prepare for the process now.]
If you are on an iOS 8 beta, you should upgrade to the iOS 8 release right away, as the iOS 8 betas expire at a specific date in the future. The iOS 8 GM does not expire like the betas, but it is still a good idea to upgrade while you are thinking about it.
