Chronic Dev hacker Pod2g has confirmed on Twitter that his untethered jailbreak exploit works on iPhone 4 handsets with iOS 5.0.1 installed. This particular firmware version is the newest one yet.After sending the entire jailbreak community into a frenzy last week with the confirmation of an untethered hack for iOS 5 on iPod touch fourth-generation devices, Pod2g managed to successfully test the same feature on an iPhone 4 running the newest version of Apple’s mobile operating system.
“Got an untethered iPhone 4 running iOS 5.0.1,” Pod2g
wrote.
For those who have been postponing the installation of Apple's newest firmware, “Feel free to update,” the hacker added.
In an earlier tweet, Pod2g had also mentioned the iPhone 4S and the iPad 2 - the two devices that remain untampered with to this date (well, more or less).
The A5-powered gadgets have proven to be tough nuts to crack for both Chronic Dev and the iPhone Dev Team whose Musclenerd also confirmed some jailbreak progress last week.
An untethered jailbreak is a type of hack where the user’s device doesn’t require a connected reboot to an external device capable of executing commands on the device.
Although many device/firmware combinations can use an untethered jailbreak, the most recent version that currently supports this is iOS (4.2.1).
Devices as new as the iPod touch 4G and the second-generation Apple TV have known bootrom exploits. Several iPhone 3GS models with old bootroms have supported untethered jailbreaks for a while now.
However, newer devices are more problematic. And by newer I mean even those as old as the iPhone 3GS with new bootrom, or iPod touch 2G (also new bootrom). These and the third-gen iPod touch have bootrom exploits that are limited to a tethered jailbreak.
Once Chronic Dev rolls out the goods, this will all be a thing of the past.
