iOS 8 is the most recent firmware created by Apple for its mobile devices. It was officially presented on June 2, and released to public on September 17, 2014. A lot of people have already upgraded their iDevices to this operating system version and you can also install iOS 8 on a jailbroken iPhone, iPod touch or iPad.
We’ll describe how to update a jailbroken iPhone to iOS 8, and you can follow the step-by-step instruction and get all the benefits of the new firmware on iPhone 5S, 5c, 5 and 4S.
Don’t worry if you tried to update to iOS 8 via OTA and saw “Checking for Update” message instead of the firmware file. This happens with jailbroken gadgets, because hackers turn off OTA updates to help users who have a jailbroken device to not update by accident.
In other words, you can upgrade your jailbroken iPhone to iOS 8 only manually through iTunes.
