This one is a breaking one. Chronic Dev Team has found 5 userland jailbreak exploits for untethered jailbreak on iPhone 5 and iPad 2. Joshua Hill as known as p0sixninja has announced this during his talk at MyGreatFest. So wait for Greenpois0n iOS 5 untethered jailbreak for iPhone iPad and iPod Touch.
P0isixnija and iOPK were there at MyGreatFest to represent Chronic Dev Team. Unfortunately Pod2g was unable to make it to the event. We are now much relaxed to hear that their team has found 5 userland exploits to jailbreak iPad 2 and the upcoming iPhone 5. Their exploits are already being tested on the iPad 2 and are working properly.
You can find the difference between a userland exploit and a bootrom level exploit at the bottom of this post. What we need to clear and what many big jailbreaking websites are misunderstanding is that these userland jailbreaks can be patched by Apple with new software updates. So they will be waiting for iPhone 5 and iOS 5 public version before they release it for both iPhone 5 and iPad 2.
According to their key member Joshua Hill, its a record breaking number of exploits found by their team. And yes you will get these jailbreaks for A4 based devices as well which includes iPhone 4, iPod Touch 4G and iPad 1.
According to Joshua, their team will be able to release untethered jailbreak for iOS 5 for public version. Of course they need to have iPhone 5 before they can test their exploits on the latest device as well. So wait for iPhone 5 release with iOS 5 public version and an untethered jailbreak for it by Chronics.
They have not announced whether they will call it Greenpois0n or is it going to be a new tool in front of this exploit. But no cares about its name, its the exploit which matters and its working.
Joshua also mentioned their issues to expand their team. They need funding to involve more hackers in their team.
Difference between Bootrom and Userland exploits:
We are not going to go into the details and depth as we are writing it for the people who are a little less technical. Bootrom level are the ones which are hardware based exploits and cannot be fixed until there is a change or upgrade in the hardware by the company. For example, if Geohot finds a bootrom level exploit for the iPad 2 device, it will not be possible to fix it as Apple cannot revise the hardware. If they upgrade the hardware in the iPad 3, then it will be fixed otherwise no chance. Such vulnerabilities which results in a hardware based exploit are normally complicated to find. On the other hand, User land exploits are the ones found in the software. These can be patched by Apple with software update. For example, Comex found a PDF vulnerability and developed JailbreakMe to jailbreak iOS 4.3.3. Apple patched his exploit by releasing iOS 4.3.4 and iOS 4.3.5.
