Apple’s new iPhone operating system, iOS 11, includes a feature called “Erase All Content and Settings.” This allows users to completely erase their iPhone, including any data stored in iCloud. However, there are some potential consequences to erasing your iPhone this way. First of all, any data stored in iCloud on your other devices - such as your iPad or Mac - will be erased with your iPhone. This means that if you want to keep any of that data safe, you’ll need to backup it first. Secondly, if you have any passwords or other sensitive information saved on your iPhone, erasing it will delete that too. Finally, anything installed on your iPhone through App Store updates or third-party apps will also be lost. So should you erase your iPhone before upgrading to iOS 11? That depends on what you plan to do with the device afterwards. If you just want to get a new one and start over without all the old data, then by all means erase it before upgrading. But if you’re planning on using the old phone for something else - like keeping some old photos or videos - then it might not be worth losing everything just because you upgraded to iOS 11. ..
