[h2]Some Background Story[/h2]
Jailbreaking is a process that allows iPad, iPhone and iPod Touch users to run third-party unsigned code 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, although this is quickly remedied by restoring the device in iTunes.
Cydia founder Jay Freeman estimates that over 10% of all iPhones are jailbroken.
The first jailbreaking method was released on July 10, 2007, and a month later the first third-party game was released for the iPhone and iPod Touch.
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.
In February the Italian hacker Zibri found the most important key inside the iPhone which then lead to all upcoming jailbreak methods. Zibri himself coded and freely distributed ZiPhone, the easiest jailbreak of all. 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. In January 2009, the iPhone Dev Team commenced work on jailbreaking the iPod Touch 2G. On March 17, 2009, Apple announced the release of iOS 3.0, which remained unbroken until the iPhone Dev Team released PwnageTool 3.0 and redsn0w 0.7.2 three months later. 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; the iPod Touch would remain unhacked for a month, until the release of George Hotz's blackra1n.

JailbreakMe: http://www.jailbreakme.com/ (Visit this site on Mobile Safari)
Works for: 4.0 - 4.3.3 (All iDevices including iPad 2)
Originally based on SHAtter, but is now using the USB Bootrom which Limera1n is based off of. Giving up two valuable bootrom exploits in one go is not worth it.
Works on 4.0 and ALL newer firmwares released in the future
greenpois0n is recommended over limera1n as it is more reliable, and more stable. Not to mention that it needs less hassle to jailbreak the device.
Tethered: Only for firmware > 4.2.1
A bootrom based jailbreak tool that is fors for ALL DEVICES at the moment, until Apple releases a new line of hardware revisions to patch this.

For iPhone 3G, iPod Touch 2G, iPhone 3GS, iPhone 4, iPod Touch 3G, and iPod Touch 4G with the current unpatched bootrom, all firmwares can be jailbroken using redsn0w.
Q: Where can I download iOS version X.Y.Z for my iDevice?
Q:What is the differences between a "tethered" jailbreak and a "untethered" jailbreak?
A:Think of a tetherball: It's a ball tied to a pole by a chain. Tethered jailbreak means that the device will go to the "connect to iTunes" screen every time it was rebooted, and requires you to run the jailbreak tool again. Untethered means that the process is one-time. You can restart your device all you want, and it will boot fine.
Q: Which devices supports the untethered and permanent "24kpwn" exploit?
A:Launch iPhone 3GS with older bootrom, all iPhone 3G/original, iPod Touch 2G/1G with model MBXXXX
Q:If I update my jailbroken iDevice to the latest firmware for jailbreak, will I lose all of my data?
A: Unless you selected "Restore", then no, your songs, videos, photos, notes, appstore apps, and all other "official" content will not be erased. However, ALL CYDIA APPS WILL BE REMOVED.
Q: OMFG If I screw up, will my device turn into a brick permanently?? :ohdear:
A: No. You can always restore your device by placing it into DFU mode.
Q: Can I downgrade my firmware to a previous version?
A: For iPod Touch 2G, iPhone 3G, and devices that are older, you can. For newer devices, they cannot be downgraded unless you have a "SHSH blob" for the specific version you are attempting to downgrade saved. More information regarding on this topic will be added later.
Q: How can I update to the latest firmware and preserve the 1.59.00 baseband firmware for my iPhone 4 in order to use ultrasn0w at the same time?
A: Please read this article CAREFULLY: http://thefirmwareumbrella.blogspot....nd-update.html
Q: When I use redsn0w, the jailbreak process gets stuck at "Uploading ramdisk"
A: Run redsn0w as administrator, and if necessary, under Windows XP SP3 compatibility mode.
Q: I don't like SSH. How can I get files onto my device without it?
A: The easiest way would be downloading Total Commander and an addon for it called "T-Pot". This allows you to upload files to your iDevice to anywhere, including the root directories if your device is jailbroken.
Q: When I tries to jailbreak my device, it didn't work/I got an error/how to solve this problem?
A: Be descriptive, we cannot read your mind over tcp/ip (or at all)
:siren:STOP POSTING SCREENSHOTS OF YOUR HOMESCREEN, LOCKSCREENS, AND ETC:siren:
There is a designated thread for it, so use it. No one in this thread cares about how you pimped out your device; they only clutter up the thread. If you would like to tell us that you were successful with your jailbreak process, that's great, go for it. Attaching a photo of your homescreen is not necessary.
