What is Tethered? What is a Bootrom? ANSWERS HERE!

This video explains some jailbreak terms that you may need to know for the next jailbreak.

Jailbreaking is a process that allows iPad, iPhone and iPod Touch users to install homebrew applications on their devices by unlocking the operating system and allowing the user root access. Once jailbroken, iPhone users are able to download many extensions and themes previously unavailable through the App Store via unofficial installers such as Cydia. A jailbroken iPad, iPhone or iPod Touch is still able to use the App Store and iTunes.
Jailbreaking is different from SIM unlocking, which, once completed, means that the mobile phone will accept any SIM without restriction on, for example, the country or network operator of origin. Jailbreaking, according to Apple, can void Apple's warranty on the device,[1] although this is quickly remedied by restoring the device in iTunes.
Cydia founder Jay Freeman estimates that over 10% of all iPhones are jailbroken.[2]

2007
The first jailbreaking method was released on July 10, 2007,[3] and a month later the first third-party game was released for the iPhone and iPod Touch.[4] Three months after the initial jailbreak, another method was discovered, which led to a cat and mouse game between Apple and hackers to patch and exploit security holes.[5]


2008
In February the Italian hacker Zibri found the most important key inside the iPhone which then led to all upcoming jailbreak methods. Zibri himself coded and freely distributed ZiPhone.[6] Upon the nearing release of OS 2.0 (previously iPhone OS), a hacker group called the iPhone Dev Team released a jailbreaking application named PwnageTool that used a graphical user interface to jailbreak 2G and 3G versions of the iPhone, and the first generation of iPod Touches then available.[7] PwnageTool continues to be developed as of iOS 4.0.1.[8]

2009
In January 2009, the iPhone Dev Team commenced work on jailbreaking the iPod Touch 2G.[9] On March 17, 2009, Apple announced the release of iOS 3.0,[10] which remained unbroken until the iPhone Dev Team released PwnageTool 3.0 and redsn0w 0.7.2 three months later.[11] The iOS 3.1 release in September 2009 again disabled jailbreaking, which was followed by a new version of PwnageTool able to jailbreak all devices except the iPod Touch 3G;[12] the iPod Touch would remain unhacked for a month, until the release of George Hotz's blackra1n.[13]
[edit]

2010
On February 2, 2010, Apple released iOS 3.1.3, once again blocking jailbreaks. However, most iPhone and iPod Touch models can be downgraded. The iPhone 3GS and iPod Touch 3G can be downgraded only if the user saves the SHSH blob of their device with Cydia. Users can download the 3.1.2 firmware and then jailbreak with Blackra1n RC3.
On March 20, 2010, Wii homebrew developer Comex released the video "Spirit" showing an iPod Touch 3G booting up while jailbroken, or with an untethered jailbreak as opposed to the tethered jailbreak which George Hotz's Blackra1n used. He announced it would be a userland jailbreak, a much lighter and easily patchable jailbreak not used since 1.X firmwares. He said it worked perfectly fine for the iPod Touch 3G and the iPhone 3GS, and that it would probably work for the iPad too, when it is released.
On March 25, 2010, Geohot found another exploit to jailbreak (untethered) iPod Touch 3G and iPhone 3GS (MC Model) in software 3.1.3+. He said that the jailbreak will be entirely software-based, and was later revealed as "limera1n". The website has a green/lime raindrop on the screen (possibly becoming the link to download the limera1n application once it is released). However, George Hotz retired from jailbreaking before the completion of limera1n.
On April 9, 2010, shortly after the Chronic Dev Team's announced jailbreak, Geohot revealed another jailbreak for iPad Wi-Fi model, possibly untethered. The name of Geohot's jailbreak program was rumored to be Limera1n, and has no announced release date.
jailbroken for life (although it only makes a tethered jailbreak).[25][26]
