The wait for a complete, untethered iOS 4.2.1 Jailbreak solution for newer bootrom iDevices is almost over. With the last iOS releases becoming more difficult to break among other issues, it appeared newer bootrom iDevices would be stuck [no pun intended] with only a tethered Jailbreak for iOS 4.2.1
The devs are still working hard, but thanks to a friendly exchange of dev banter, it appears an untethered solution is on the way in the form of imminent releases of GreenPois0n & RedSn0w.
It all started on January 14th with a friendly barrage of tweets between MuscleNerd of the Iphone-Dev Team and p0sixninja from the Chronic-Dev Team resulting in a challenge, Ninja Vs. Nerd:
On January 21st and only seven days in to the "10 or 20" day time frame, pod2G on the Chronic Dev team side sent this tweet regarding GreenPois0n:
The iPhone-Dev team sent the following tweet regarding Monte via RedSn0w:
Based on recent tweets, here is what we know:
*these releases do not burn an exploit
*RedSn0w is ported to iOS 4.1 SHSH
*GreenPoison & RedsnOw will NOT require SHSH blobs for 4.2b3
*RedSnow will require SHSH blobs for iOS 4.1, meaning you will have to already be Jailbroken on iOS 4.1
*Redsn0w usually follows up the Mac release with a Windows Release
*GreenPois0n is a Windows only Jailbreak
I will keep you posted on the latest developments as soon as I have them.
In the meantime, prepare your iDevice for Jailbreaking.
Here's how Bruce T Does it:
1. Be sure you are jailbroken at iOS 4.1 and your 4.1 SHSH shows up in Cydia.
2. Backup your apps from Cydia using PKGBackup.
3. Create a free DropBox account to use with PKGBackup.
4. Run PKGBack up using both the option to save in contacts and to save in DropBox.
5. Backup your iDevice in iTunes.
6. Sit and wait.
An update to How Bruce T Jailbreaks iPhone page will be available as soon as the Jailbreaks are released.
