On Wednesday, September 17th, Apple released iOS 8 to most mobile devices. If you have an iPhone 4, you are out of luck, but if you have an iPhone 4S or newer, you will be prompted for this update.
At this time, Student Affairs ITS is advising against the upgrade if you are still using an iPhone 4S. While this device can run the new iOS, it will lack some of the newly release Apple apps and some users have reported the iPhone has slowed down. Upgrade at your own risk!
As for everyone else, the only issue you may run into is that downloading the update over the air will require 5.8GB of space; which not everyone will have! This will cause you to have to go through and delete items such as apps, music, or photos before being able to download and install the update.
