Comex, developer of popular jailbreaking tool, Spirit jailbreak for iPhone OS 3.1.3, iPhone OS 3.1.2 has discovered another userland jailbreak in iOS 4 similar to the one used in Spirit jailbreak.
iPhone hacking experts planetbeing, chpwn and MuscleNerd of the iPhone Dev Team have managed to get root access on iPhone 4 using comex’s userland jailbreak.
planetbeing was the first to announce the breaking news on Twitter:
Think I’m the first one I know about to get a root shell (and SSH) on iPhone 4, using poor @comex’s code (since he has no iPhone 4)
MuscleNerd of iPhone Dev Team has confirmed the news and has followed it up with a screenshot of Cydia running on iPhone 4:
Congrats to @comex for another userland JB http://is.gd/d5N6I <– hi-res Cydia via @planetbeing & @chpwn iPhone4s
However, this does not mean that iPhone 4 can also be unlocked. iPhone 4 comes with a new baseband, which will require Ultrasn0w to be completely rewritten to work on iPhone 4.
MuscleNerd of the iPhone Dev Team has published the screenshot of full root access on iPhone 4, which is possible only if it is jailbroken:
Thanks Jasmart for the tip!
