Official DevTeam comments:
RedSn0w
redsn0w allows owners of A4+earlier devices to install rocky-racoon two different ways:
backup/restore method similar to Absinthe and cinject
its traditional limera1n-based ramdisk install. If you have a lot of media on your A4 device (music, movies, TV shows, etc), then the ramdisk method is preferrred because it avoids any possibility of later problems related to syncing to iCloud (including Photo Stream and Music Match). The ramdisk method is not available for A5 devices or later because limera1n can’t be used. If you’d like to use redsn0w’s ramdisk method, just be sure to put the A4 device in DFU or Recovery mode before starting redsn0w (otherwise it will immediately start to use the backup/restore method).
We’ve also added a new redsn0w feature specifically for those who got in on the SAM unlock: you can now include your SAM tickets as part of your initial ramdisk jailbreak of iPhone4 or earlier, or alternatively you can upload your SAM tickets to any device after its been jailbroken. redsn0w accepts either the individual SAM activation ticket plist file, or the entire zip file created by redsn0w’s “Backup” button. As usual, redsn0w continues to cover all of its previous jailbreaks and untethers (so redsn0w-0.9.12b1 covers everything from 5.1.1 all the way back to 4.1).
PwnageTool
PwnageTool also avoids any possible sync issues, but again it applies only to A4+earlier devices. If you unlock your iPhone with ultrasn0w or a commercial method, you must use PwnageTool to avoid updating your baseband otherwise you’ll lose the unlock. PwnageTool will also jailbreak+untether the AppleTV2,1 5.0_2B206f (unless you customize the IPSW further, you’ll have just basic SSH access to the device).
MuscleNerd, a hacker from DevTeam, recently published a screenshot of anticipated jailbreak utility PwnageTool 4.1. It will support iOS 4.1 and will be able to preserve old baseband for unlockers, who have not updated to iOS 4.1.
From the screenshot we can tell that PwnageTool 4.1 will support:
Here’s his message from twitter:
PwnageTool screen about to get a lot more crowded again due to limera1n exploit http://is.gd/g7P9G (unlockers win most)
New PwnageTool was expected to be released last weekend, however it was delayed.
The iPhone DevTeam have probably found a new method to jailbreak Apple devices with the A4 chip. This includes such devices as iPhone, iPad, iPod and Apple TV. This is great news!
MuscleNerd tweeted.
Think we’ve figured out a way to extend PwnageTool+limera1n+@comex hacks to untethered JBs for all future A4 firmwares
MuscleNerd from DevTeam has posted a video preview of the new PwnageTool upcoming release. The new PwnageTool will use Geohot’s Limera1n exploit and will let users who need unlock to obtain it. Here’s MuscleNerd message from twitter:
Nerd alert: geohot’s limera1n in PwnageTool… iTunes restoring iPad to pre-JB 3.2.2 (AppleTV next!) http://is.gd/g37Lm
Let’s watch the video:
The release of PwnageTool is scheduled for this Sunday.
