As clueless I was, I didn’t know that iOS 5 came out with this new feature, which was the ability to update your iPhone’s/iPad’s iOS version via Wifi without the need to plug-in to iTunes. It’s very easy to do it, just follow the following steps.
- Go to your iPhone’s “Settings” option
- Select “General“
- Then select “Software Update“
- The phone will search the servers for the latest patch
Select “download and install”
Make sure that your phone is also plugged into a power source
Wait for the download to complete and voila, your iOS device is now updated.
