Here are some things to watch out for when you update your devices tomorrow: - The update will most likely be released at 10 AM PST. - Update servers may be slow. Be patient. - Back up your devices first using any preferable method. - Have the update file (IPSW) saved to your computer (Mac or PC) if you are updating multiple devices of the same model identifier (eg iPhone8,1 this is not the iPhone 8, it is the 6s!). - Use Apple Configurator to update multiple devices with the same model identifier (see above). - Have your Apple ID credentials ready. Reset your password if you forgot it. - Don’t update your apps until you accept the new App Store terms and conditions. Apple updates these yearly following a major software update. This is the most common problem for not being able to update your apps on release day. - 32 bit apps are not supported. See the front page article for more information. - Report any and all bugs observed in the build issued. - Update the App Compatibilty thread with apps that offer new features in iOS 11. - If you have any issues or questions, ask and use Apple's support documentation. Don’t just write it off as “the update is broken” or “not working”. There will most likely be a thread similar to the ones for beta seeds with new features and bugs listed. Please note that this thread is intended for those who are in fact updating to iOS 11. If you are not updating, refrain from posting and/or complaining. Update issues should be discussed here. Only offer tips, advice and positivity! If I missed anything, please add it. Good luck!
