Check in With IT
If you use your iPhone or iPad for work and you have an IT department, you'll probably want to check in with them before you download iOS 11.4.1.
Enterprise problems are extremely common after Apple releases a new version of iOS and we expect to see numerous issues popup in the days ahead.
We highly recommend getting in touch with IT to see if the latest iOS 11 update is safe for you to use. If you're lucky, they've already been testing the software.
If you don't have an IT department or a tech on site, you might think about asking guinea pigs your co-workers for feedback about the apps and services you use the most.
