Definitely, the news about jailbreaking process breakthrough is not just for iPad holders, but for all kind of iPhones as well. But since, I am faithful Droid fan, I personally care about iPhones much less. So, October 10 and October 11 should be great days in the technological history of iProducts. Because the solutions to unlock the full power of these devices are coming...
What is Jailbreaking?
Jailbreaking is a process that allows iPhone, iPod Touch, and iPad users to run any code on their devices, as opposed to only that code authorized by Apple. This process permits users to install homebrew applications on their devices by unlocking the operating system and allowing the user root access. Once jailbroken, iPhone users can 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.
Does Apple like the users’ ability to bypass their filters and use the commercial applications for free? Definitely, no. Therefore, they release once a while software updates, which cause the jailbroken devices to be returned to the original state. The severe competition between freelancing hackers and hackers employed by Apple continues.
Is that legal to Jailbreak your device?
All the law obedient citizens would be surprised, but the answer is YES. You have a freedom to unlock the Apple device, and Apple has a freedom to prevent you from doing that, but not through legal and enforcement approaches, but purely through technological solutions only.
Jailbreaking an iPod or iPhone in the United States is legal "fair use", and does not violate copyright laws defined by the Digital Millennium Copyright Act. In response to a request by the Electronic Frontier Foundation, the U.S. Copyright Office explicitly recognized an exemption to the DMCA to permit jailbreaking in order to allow iPhone owners to use their phones with applications that are not available from Apple's store, and to unlock their iPhones for use with unapproved carriers. Apple had previously filed comments opposing this exemption and indicated that they did consider jailbreaking to be a violation of copyright (and by implication prosecutable under the DMCA). Apple's request to define jailbreaking as a violation of copyright was denied as part of the 2009 DMCA rulemaking. In their ruling, the Library of Congress affirmed on July, 26, 2010 that jailbreaking is legal under U.S. copyright law.
Tim Wu, a professor at Columbia Law School, argued that jailbreaking is "legal, ethical, and just plain fun." Wu cited an explicit exemption issued by the Library of Congress in 2006 for personal unlocking, which notes that locks "are used by wireless carriers to limit the ability of subscribers to switch to other carriers, a business decision that has nothing whatsoever to do with the interests protected by copyright" and thus do not implicate the DMCA. Wu did not claim that this exemption applies to those who help others unlock a device or "traffic" in software to do so. As of July 26, 2010, The U.S. Copyright Office has approved exemptions to the DMCA that allow iDevice users to Jailbreak their devices legally. These exemptions also allow phone users to unlock their phone in order to switch carriers. It is still possible Apple may employ technical countermeasures to prevent jailbreaking or prevent jailbroken phones from functioning, but they will not be able to sue users who jailbreak.
GreenPois0n and LimeRa1n
All the iDevices fans were expecting the new jailbreak solution from Chronic Dev Team, and recently the release date of the Greenpois0n has been announced as October 10, 2010. It supposed to cover all iOS 4.1 Devices for life including Apple T.V 2G (which means a solution for all iPad 3.2.2 holders as well). There are two more important points to bring in: the solution should be for life, so Apple future efforts should not harm the unlocked devices, and that the solution is untethered meaning that users do not have to plug the jailbroken device into a computer every time it needs to be restarted (as in some previous software releases.
The spice to the picture added the fresh news on the competitive solution LimeRa1n, created by Geohot, the famous guy who unlocked the iPhone and also creator of blackra1n. This new exploit supposed to jailbreak all iDevices including iPhone 3GS and iPod Touch 3G which even the SHAtter exploit and GreenPois0n cannot jailbreak.
With Limera1n and GreenPois0n around the news, one thing is sure that we will definitely get the jailbreak for iPhone 4, 3GS, iPod Touch 4G, 3G and iPad with in next 2 days. It can either GreenPois0n or Limera1n or even both. The Chronic Dev Team did note that since Geohot's LimeRa1n is a different exploit, it will effectively "burn" it. This is because Apple will be tipped to the new exploit. With rumors of a Verizon iPhone coming in early 2011, this could enable them to close the bootrom exploits, both of them, prior to that device's rumored launch.
Which jailbreak I will recommend? At the moment it is still unclear even for the people which are more experienced on the topic than I am. I would recommend not jumping to the first trials, but waiting to see what the results of both GreenPois0n and LimeRa1n are. Wait couple of days and choose jailbreak which is the easiest, fastest, and safest.
The plans have changed fast. Jailbreak limera1n was released today for 4.1 iDevice users with some limitations, like supported only for Windows OS, while the previously announced dev-team jailbreak, which was due out tomorrow, may be put on hold while the team works on revising their tools for the limera1n exploit rather than exposing multiple exploits that will quickly be patched.

There is a confirmation that GreenPois0n jailbreak will be delayed. The latest update from Chronic Dev Team Blog:
Thanks to the irresponsible antics of geohot, we will have to delay the release of greenpois0n (new ETA = as soon as possible), so that we have time to clean up his little mess and integrate the exploit he uses in limera1n into greenpois0n. This way, we can save SHAtter for future devices that may still be vulnerable to it.
We know that this is not what some people want to hear, but due to geohot needing to feed his ego (as usual) and revealing his limera1n exploit, we do not have any other responsible options.
