Check With IT
If you use your device for work and you have an IT department, its a good idea to check in before you download iOS 10.3.3 to make sure apps and other services are working properly.
iOS enterprise problems are extremely common, particularly after new iOS releases and we expect to see and hear about a number of problems as we push away from the iOS 10.3.3 release date.
To help prepare, we recommend getting in touch with IT to see if the iOS 10.3.3 update is safe for you to use. If you're lucky, they're already been testing the software.
If you don't have an IT department or a tech on site, you might think about asking your co-workers for feedback.
