Jailbreak Terms A - Z
If you guys think of any more, please feel free to post them up and we'll add them!
Absinthe Greenpois0n jailbreak utility used to jailbreak A5 devices such as the iPhone 4S and iPad 2
Ac1dSn0w Jailbreak tool released in 2011 by Manuel Gebele. Originally released to support a tethered jailbreak for iOS 5 (tethered). Will most likely be updated to support other devices.
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 essentially the part of your device that controls the antennae. This has everything to do with your service and signal. This is why most unlockers have to be extremely careful when upgrading. If the baseband changes, it can permanently keep them from achieving an unlock. This is the main reason most unlockers tend to favor PwnageTool. It creates a custom firmware bundle for you to upgrade to that doesnt upgrade the baseband, only the main OS. If you are running on a legitimate carrier and dont care about unlocking, the baseband it typically less of a concern. Wifi and Bluetooth dont run on the baseband either, so iPod touch or iPad owners typically dont have concerns when it comes to new baseband versions. Tools like redsn0w and sn0wbreeze are capable of preserving your baseband so during an upgrade the firmware can be updated while the baseband remains in tact. This is something desirable when you need to achieve an unlock.
BigBoss One of the largest and most well known repositories in Cydia
BiteSMS A jailbreak application available in Cydia that adds more functionality to the default messaging app including quick reply and quick compose functionality. BiteSMS also offers users the ability to purchase credits to use towards international texting that are typically cheaper than paying carrier rates.
blackra1n A jailbreak utility used to jailbreak devices running iOS 3.x
Blobs A lot of people ask about this one and why Cydia wants to save them. When you upgrade firmware in iTunes, youll 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. SHSH blobs save you from this headache. It will basically give iTunes a fake hand to shake, which in turn, makes iTunes think your restore has been verified. This can be a life saver if you accidentally upgrade and need to downgrade. TinyUmbrella will save SHSH blobs to the Cydia server as well. I highly recommend saving your blobs for every firmware version in case you ever find yourself in this predicament. We have posted a guide on how to save SHSH blobs using Tiny Umbrella.
Bootloader This refers to the baseband bootloader. It is the code that is run before the baseband firmware. This is the code that is responsible for updating the baseband and signature checking.
