Another day, another jailbreak related tweet sends the world into chaotic meltdown. I have to be honest, I am finding it difficult to keep up with who is working on what, and who is working in collaboration with who.

iOS 4.3 WM

So just what is this tweet that I have mentioned? Well, Stefan Esser (a.k.a @i0n1c) posed a question to his followers querying whether or not any of them believed that an untethered jailbreak for iOS 4.3.5 would be welcomed with open arms. Judging by his follow up tweet, shown below, his followers unanimously decided that producing an untethered jailbreak for what is now an outdated version of iOS was not the way forward.

So, in typical style that a large number of people have associated with the German security expert, his tweet has indicated that he has decided to go ahead regardless and produce the untethered jailbreak that his own followers inform him they don’t want. Madness you say? Well maybe, maybe not. As long as the production of such a jailbreak doesn’t burn an exploit that could be used elsewhere, I really don’t see the harm in the creation of a 4.3.5 untether. Having said that, it is important to note that i0n1c has this nag of trolling his Twitter followers. He has done it a number of times in the past, and he may just be joking around this time too.

A lot of users took the plunge and upgraded to iOS 5 when it was made public, simply because it was such a large update over previous versions of iOS. With new features such as Notification Center and the new Reminders application, the pull to upgrade was just too much for some. But then you have the user base who remains on iOS 4, partly because they are running old hardware, and partly because they just don’t feel the need to update their firmware right away. The production of such a jailbreak would no doubt have its users and be appreciated by a large base of people.

So just who is Stefan Esser? Well, he is first and foremost a German security researcher with a background in iOS development. He has developed a tool named Antid0te which is an ASLR for jailbroken devices, however due to the inclusion of ASLR in iOS 4.3 this tool was never released. He is also responsible for writing code that can untether jailbreaks which was used in updated versions of Redsn0w and PwnageTool by the iPhone Dev Team.

Until then, you can follow our instructions posted here on how to jailbreak using Redsn0w, or here using Ac1dSn0w (instructions with Ac1dSn0w Beta 2 here), or here using Sn0wbreeze.

So, he has pedigree. I guess those users are maybe currently using a tethered jailbreak for iOS 4.3.5 can sit back and relax knowing that Mr. Esser may soon have you covered.
