With the official release of iOS 4.2.1 now in the record books, the Dev-Team “gobbled” the new firmware down and “spat up” a new blog post, which — after the usual “ultrasn0w users sit tight for now” message — reads in part:
The best news of all is for owners of iPhone3G, older iPhone3GS, and non-MC iPod touch 2G. 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.
Next are the owners of all the more recent devices. The good news there is 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). The bad news is that right now, the 4.2.1 jailbreak is *tethered* on all of these recent devices.
ultrasn0w unlock: After redsn0w is officially released with the new Cydia and kernel patches, we’ll be able to assess the unlock situation. It’s already looking very promising though, so expect the unlock for the 3G and 3GS to be coming this week. The i4 unlock is taking more effort though, and no further concrete info is available about that yet.
The blog entry concludes with the best present of all: the availability of redsn0w version 0.9.6b4 for OS X and Windows.
With news like this, the Dev’s deserve their own float in the Macy’s Thanksgiving Day Parade. Unfortunately, most people would probably mistake it for Spongebob Squarepants…
