An unlock for iOS 4.2.1 is almost ready to go, signals iPhone Dev Team member Musclenerd, via Twitter. Apparently, Apple tried to block their ultrasn0w unlock tool via “aggressive compiler optimization,” but the Team was able to crack it and is gearing up to release a new version that will do the trick for iOS 4.2.1 users, albeit only for those wielding an old-generation handset.

“Finally got ultrasn0w working fully on 4.2.1,” Musclenerd writes on Novemver 27. “Apple inadvertently(!) broke ultrasn0w via aggressive compiler optimization,” the hacker explains.

In a separate note that hit the micro blogging service just minutes ago, Musclenerd adds: “When we update ultrasn0w today, 100’s of thousands (maybe millions?) will see red badge. Trying to make it safe for all.” More »

The latest update from the famous hackers, titled “Thanksgiving with Apple”, reveals that “The best news of all is for owners of iPhone3G, older iPhone3GS, and non-MC iPod touch 2G.”

The Team explains that, “Due to a combination of our original pwnage2 exploit, the arm7_go exploit, 24kpwn, and limera1n, your device is “just as jailbreakable as ever.” You reap the full benefit of an untethered 4.2.1 jailbreak.”

However, the same thing cannot be said about owners of a new-generation device, or “more decent devices”, as the Team likes to call them.

There’s good news and bad news here as well.

For starters, the Team claims that “due to geohot’s limera1n exploit, all recent devices can be jailbroken (this will be true until Apple released new hardware that fixes geohot’s limerain exploit in the bootrom).” More »
