How to update your iPhone/iPod/iPad without iTunes via OTA! [iOS 5 and above]

Here’s how you could update your iPhone / iPod / iPad through Over-the-Air update without iTunes on iOS 5 device. The OTA can be performed with either WiFi or 3G networks. 

With iOS 5, Apple introduced Over-the-Air updates for its iOS devices, and the updates are not Delta updates instead of the regular updates that Apple gives us. These updates can be installed directly on your iOS devices like iPhone, iPad or the iPod Touch with just a few steps, as and when the updates are pushed to the devices.

Rather than the traditional way of downloading a IPSW to your iTunes and then restoring your device with the new firmware, the OTA updates are a huge feature for the iOS device owners. And what’s more interesting is that, these updates can be done with either 3G or WiFi networks right on your device. Now, let’s see how this could be done:

• Launch Settings
• Tap General
• Now, you’ll find a new tab on this page. Tap Software Update

• If some update is available, the just Click on Download and Install.
• This would update your iOS device to the latest firmware.
