Earlier we told you that the exploits by Chronic Dev Team for untethered iOS 5 jailbreak has been patched by Apple. These were the same exploits they promised during the MyGreatFest (now JailbreakCon) conference.
Chronic Dev team has also released cDev Crash Reporter tool. What this tool does is it allows users to send Chronic Dev Team crash reports of their iOS devices. Apple also use the same crash reports to find different vulnerabilities and they try to fix them. Chronic Dev Team is using the tool to get these crash reports from the users. This will help them find vulnerabilities. Unlike Apple, they will use these vulnerabilities to inject unsigned code for untethered iOS 5.0 JB.
We have explained the whole scenario. Now what we have explained is told to us by the Chronic Dev Team. We are not sure whether they will be successful using this approach to find vulnerabilities for untethered 5 jailbreak. But apparently their approach seems fine enough.
On the other hand, Stefan Esser (@i0n1c on Twitter), the developer behind the untethered iOS 4.3.1 / 4.3.2 / 4.3.3 jailbreak has a totally different opinion. According to Esser, these crash report dumps from users will not help finding exploits. This is what he has tweeted:
We can assume that he has his own way and approach to find vulnerabilities. But in short he does not think that crash report dumps can help them. Let us see if we can get some response from Chronic Dev Team key front person Joshua Hill (P0sixninja) on it.
Stefan Esser has also made it clear that by this he does NOT mean untethered iOS 5 jailbreak is not possible.

Let us see how Chronic Dev Team responds to it. Their last tangible contribution to jailbreaking was Greenpois0n for iOS 4.2.1 untethered jailbreak that was simply awesome. Chronic Team’s another key member Pod2g has found another vulnerability that may result in iOS 5.0 untethered but apparently the work on it is in a very preliminary stage.
On the other hand, iPhone Dev Team has also found vulnerabilities to jailbreak iOS 5 untethered on iPhone 4S and iPad 2 but that too seems to take a little time before they show any intention for public release.
