From time to time, Apple introduces major and minor updates to their operating system, referred to as iOS for iPhones, iPads and iPods. These upgrades are typically important and you should do them.
These days you will get an App Store notification on your device and you can do the upgrade over the air (OTA). This can be a slow process so it is wise to do the upgrade while on Wi-Fi or by connecting to iTunes. However, there are some things you can do BEFORE upgrading.Before upgrading your iOS device (iPhone, iPad or iPods) you should do a few simple things to prepare and avoid or be able to quickly get through a crisis.
- Do some simple house cleaning by removing apps you no longer use. Just delete from the device and NOT from iTunes. This will speed up the upgrade time.
- Transfer purchases from your device to iTunes. Connect to iTunes and go through the Backup and Synch process. Or right-click on your device at the left menu. With iTunes 11.x, from the Menu Bar, choose File > Devices > your device > Transfer Purchases.
- Do a Backup. From the same menu as above.
- If you haven't done so, install the latest version of iTunes. This is CRITICAL to obtain and use the latest features in the upgrade.
