BOOM! It is exciting as well was some major update in jailbreak scenario as iPhone 4 is almost jailbroken . It looks like that era of userland jailbreak is emerging which are not long lasting but are ready for quick solution. Again this time @comex has struck another userland jailbreak in iTunes 9.2 which means that every iDevice to date including iPhone 4 3GS 3G and iPod Touch 3G/2G [New Bootrom MC Models] will be jailbroken running iOS 4.
We may get an updated version of Spirit jailbreak for iPhone 4 3GS on iOS 4/4.0.1. It may get delayed because @comex wasn’t able to pre order iPhone 4. Due to this userland jailbreak, other developers like @planetbeing @chpwn has been able to get a root shell access on iPhone 4 which is a breakthrough and finally will emerge as tool to jailbreak iPhone 4.
Here is hi-res Cydia running on iPhone 4 which means that we are almost there. It should probably come out once Apple has released iOS 4.0.1 to fix signal issues.
Hats Off! To @comex and others.
Update: MuscleNerd has just updated on Twitter with an iPhone 4 screenshot being accessed with full root access.
Also, Hackers have informed that the code is in raw form and contains some proprietary code by Apple. Therefore, it will take sometime to release the jailbreak for iPhone 4.
Update: It looks like that ultrasn0w iPhone 4 unlock is delayed although iPhone 4 is jailbroken.
Update: iPhone 4 Jailbreak is now possible with JailbreakMe.
