Updating a jailbroken ipod touch
Unless you’re making a warranty claim or passing the phone on to someone who can use it on the network it is locked to, you might as well keep an eye on the jailbreak scene to ensure you can still use your phone once you’ve upgraded and re-jailbroken.
Here’s how to remove your jailbreak and restore stock i OS to your i Phone, i Pad or i Pod Touch.
In addition to i Tunes, another option for backing up from Apple is also available - i Cloud.
Using i Cloud, you're also allowed to backup the whole data of i Phone, i Pad or i Pod touch under a wireless network.
We all know that the purpose of jailbreaking your i Device is always to be able to get access, download and install apps on your i Device without restrictions, especially apps that are not available in Apple store.
However, after jailbreaking your i OS device, it also means you may lose the chance to freely update the operating system, that is mainly because most of the modern jailbreaks like Tai G do not work well with OTA updates.
