If you are part of the jailbreak community, then no doubt you have heard of the name Comex. A few weeks ago, the jailbreak community was given a nice treat as the renowned jailbreak developer released his jailbreak tool, Jailbreak 3.0. This jailbreak tool promised to be the fastest and easiest way to jailbreak your iOS device, and it certainly delivered. Aside from the convenience that it has provided, Comex’s jailbreak tool is also known as the first ever working solution to an iPad 2 jailbreak. And now as he has promised earlier, Comex has just released the source code of JailbreakMe 3.0, making it officially an open source program.
Jailbreak 3.0 is codenamed “Saffron” and was released a couple of weeks ago. Due to fact that it is the easiest method for jailbreaking, the tool was used more than 1 million times just a day after it was released. This particular tool was initially wrapped in controversy because JailbreakMe 3.0 was leaked by one of Comex’s appointed beta tester before it was released. JailbreakMe’s first ever version was released to work with iOS 1.1.1 for the iPhone and iPod touch. Version 2.0 worked with 4.0.1 for all iDevices.
JailbreakMe 3.0 is a tool that works on all iDevices available but only for iOS 4.3.3. Comex originally planned to add support for older firmware but promptly dropped the project due to time constraints. Comex did indicate that he plans to continue adding support for older firmware in the future. The tool utilizes the PDF-exploit that is found within Mobile Safari so that it can jailbreak an iOS device at root level, leaving an untethered jailbreak.
If anyone can recall, Comex has also released the source code for JailbreakMe 2.0 which is codenamed “Star”. And now as promised, he has just released the source code for the ever popular JailbreakMe 3.0. This is for the purpose of letting other jailbreak developers have a look at the code with the hopes that they can derive from it and use it to create their own tools or integrate it with their own work.
Just a few days ago, Apple has released iOS 4.3.4 which is mainly intended to patch the security exploit that the Jailbreak 3.0 has used, rendering the jailbreak tool to be useless beyond 4.3.3. With this update, Apple has also shut down the doors for untethered jailbreaks which were prevalent in iOS 4.3.X. Currently, you can tether jailbreak iOS 4.3.4 through Redsn0w.
So if you want the latest untethered jailbreak for your device then it is highly recommended that you stay away from iOS 4.3.4. We have also reported yesterday that Apple has stopped signing 4.3.3, so unless you have saved the SHSH blobs for it, then you won’t be able to restore to that particular firmware and jailbreak your device using JailbreakMe 3.0. If you are currently in 4.3.3, then we suggest that you save your SHSH blob by using iFaith, so you can restore to it anytime.
