1)Backup your iOS device
Before doing anything, you must make sure to backup your iPhone/iPad or iPod Touch to be safe, just in case you fell in any troubles.. (Note that if you choose to encrypt your backup using iTunes, along with normal data, secure information like passwords etc. are also backed up.)
I prefer making a quick backup using iCloud backup by going to Settings–> iCloud and make sure to login to your iCloud account. Scroll down and tap on ‘backup’. tap on the On/Off toggle next to iCloud Backup to enable automatic backup.
2) Jailbreakers
If you have a jailbroken iPhone or running on iOS 8.1.2 or lower you should avoid the new iOS 8.2 update as Apple has patched the exploits used by the TaiG jailbreak and PP Jailbreak, which means they can’t be used currently to jailbreak iOS 8.2.
3) How to install iOS 8.2 on your iPhone over the air (OTA):
Before you start the download, plug in your device so the battery doesn’t drain during the update process. It can take anywhere from a few mins to an hour for the update to download and install, depending on how Apple’s servers are handling the load and your internet connection. You may also want to connect your iPhone to your local WiFi network, so you don’t get charged for downloading the update over your cellular connection.
Once you are plugged in and connected via Wi-Fi, open the Settings app and tap on General > Software Update. iOS will automatically check for available updates and will inform you that iOS 8.2 software update is available.
Tap Download to download the update. Wait for the download to complete and then tap Install to apply the update. If you get tired of waiting for the download to finish (it could take a while) then go do something else. Your iPhone or iPad will continue to download the update and will send you a notification when the update is ready. Go back to Settings > General > Software Update and then tap Install Now to install the now downloaded iOS update file.
