A lot of Apple fans have already upgraded to iOS 8 following the recent release of Apple's latest mobile operating system, but for those of you that haven't, here are a few quick tips to make the experience easier.
1. Backup Your iOS Device!
Theoretically it's perfectly safe to upgrade your operating system, but you never know when something is going to go wrong. Connect your iOS device to iTunes on your computer and perform a full backup by pressing the "Back Up Now" button before you begin the upgrade process. If the worst happens, it could save you a lot of heartbreak. Should something go wrong, you'll just have to restore your iOS device from the backup to get things running again, and you won't lose any of your precious photos in the process.
2. Upgrade via iTunes
While you're already in iTunes on your computer, you might as well use it to perform the system update. For one thing, this method tends to be more reliable than updating your iPhone or iPad over the air; for another, it means you won't have to clear out nearly 6GB of free space on your device to perform the installation (which can be especially important if you have a 16GB device). After selecting your iOS device in iTunes, press the Check for Update button, then press "Download" or "Download and Update" to begin the upgrade process. If you choose "Download," you'll be able to come back later to finish the actual installation process.
3. Software Update
If you don't want to (or can't) go through iTunes on your computer, you can do it through the settings menu on your iOS device. A lot of people wait to update until they receive a notification from Apple (expect one soon if you haven't receieved one already), but you don't have to wait until then. Just go to Settings > General > Software Update. Your device will check for updates and then allow you to perform the upgrade.
4. If You Have an Older Device, Wait!
iOS 8 should work great if you have a newer Apple device. But if you have an iPhone 4S or an iPad 2, you should probably hold off for now. iOS 8 is not optimized for older devices, and is likely to give you a notable big performance hit. Hopefully, Apple will improve performance for these devices with a future update.
