Even if you consider yourself to be familiar with how jailbreaking works, it’s always handy to know exactly what we are talking about on this website. That being said, we have put together a list of the most common jailbreak terms to help get you through any tutorials where we mention something like “SHSHblobs” yes, that’s seriously a common term. Scan through our list and let us know if you have any questions regarding any of the terms on the page. If you think we missed any, please contact us.
Absinthe – Greenpois0n jailbreak utility used to jailbreak A5 devices such as the iPhone 4S and iPad 2
Activator – A jailbreak utility, available in Cydia that allows you to assign gestures to invoke applications and utilities. For example, you can set a double tap on your status bar to open SBSettings, a quick reply texting app, or any other app of your choosing that has Activator support. Most applications readily support Activator.
Baseband – The baseband is the part of your device that controls the antennae. In some cases upgrading your device may prevent you from unlocking it. PwnageTool can help prevent this and this is why many people favour it. It simple terms it will create a custom firmware (ipsw) bundle for you to upgrade so that it doesn’t upgrade the baseband, only the main OS.
BigBoss – One of the largest and most well known repositories in Cydia. This will come as a pre-installed package once jailbroken.
blackra1n – A jailbreak tool used to jailbreak devices running iOS 3.x
Blobs – When you upgrade firmware in iTunes, you’ll see at the top when you start a restore “Verifying restore with Apple”. Apple only signs current firmware versions. If you accidentally upgrade and then try to downgrade, your restore will fail. This is where SHSH blobs come in VERY handy. They basically trick iTunes think your restore has been verified. This can be a life saver if you accidentally upgrade and need to downgrade. A program called TinyUmbrella will save your SHSH blobs to the Cydia server. It is my overall recommendation that you save your SHSH blobs for every firmware update you perform, just incase! Click here to learn a little more on SHSH Blobs.
