How To Determine if Apple Is Signing Firmware
Apple signing firmware seems to be a cat and mouse game between jailbreak developers and Apple developers. Apple wants to roll out the latest updates as quick as possible and stop signing older ones to prevent jailbreak developers from hacking the older firmwares. Firmware signing is very important to install older firmware referred to as downgrading. For this reason Apple will only sign any new firmware for as little time as possible. This is one of the ways they can control which firmware we can have on our iOS devices. They want us all running the same firmware all the time. In their thinking its a way to keep users from having problems with applications they use.
Stay Ahead of Apple
In the past we could save SHSH blobs which is something else used to downgrade but due to Apple not signing firmwares but for a short time it limits the jailbreaking experience extremely bad. Now I’m no developer and don’t understand all the logistics of these things but for the most part I understand when Apple stops signing firmware you can’t install it on your iOS device anymore. For this reason we are sharing a site which can tell you at anytime if a particular firmware is still being signed by Apple. Its very easy to read in a table format so we hope it helps. We suggest bookmarking the site so you can find it anytime you need or bookmark this post. This way you can find your way back to site when you need to check a different firmware version.
