The wait is almost over as Apple is finally seeding the official iOS 11 worldwide starting Wednesday.
On Monday, Apple took Twitter for a pre-release announcement of the eligible devices as well as a reminder before getting the update. To update to iOS 11, a user only needs an Apple ID password, an iPhone passcode, and iPhone backup, power and Wi-Fi.
Back up necessary data
Since iOS 11 is a major operating system upgrade, one needs to back up all necessary data of an iPhone or iPad. The update rolls out over-the-air (OTA), so just like anything else, there is a chance that the update would go awry. Make sure backup destination is safe and secure.
To back up using iCloud, go to Settings > Apple ID > iCloud > iCloud Backup > Back up Now. To back up using iTunes, launch the app and go to the backup section under the main menu, then tap 'This Computer' and 'Apply'.
Compatible devices for iOS 11
For the list of compatible devices, refer to Apple's GIF tweet below:
As a major update, it is expected that iOS 11 will need a number of gigabytes. Make sure to free up space, at least 3 gigabytes, to ensure your device can accommodate this huge update. To know your device's memory status, head over to Settings > Devices > Storage.
