Chronic Dev Team has finally managed to get untethered jailbreak on iOS 4.2.1 supposedly without making the use of SHSH Blobs. p0sixninja, a member of Chronic Dev team has just posted a demo video of jailbroken iPhone booting untethered while running on iOS 4.2.1. Though iOS 4.2.1 untethered jailbreak using Monte technique is already available on iPhone 4, iPod Touch 4G but only for those who have iOS 4.2b3 SHSH blobs saved on Cydia server.




We hope that this new exploit will allow users to get untethered iOS 4.2.1 jailbreak on all idevices without using any type of SHSH blobs.




pod2g explains the delay in the jailbreak tool due to minor bug.




No official ETA for this next jailbreak tool is announced by Chronic Dev Team. However, it is being expected that Greenpoison will be updated to support iOS 4.2.1 untethered jailbreak instead of releasing a new tool with new name.
