This is the same post published 2 days ago except with one confirmed update that the unlock for iPhone 3G and 3GS will definitely be out this week, according to the tweet reply by @Musclenerd who is part of the iPhone Dev Team. He was replying to a user approximately 14 hours ago:
“Now that redsn0w is out, can focus back on the unlock. The 3G/3GS version should be out this week. i4 will be longer.”
There is no ETA mentioned though and our countdown timer is still running. Be sure to subscribe to us for the latest updates!
It has been really quiet in the last couple of weeks but when iOS 4.2.1 was released yesterday, everything got busy again in the iPhone jailbreaking and unlocking world.
The iPhone Dev Team had just posted a new post on their website. Please read the following as it provides extremely important information for jailbreakers and unlockers.
With Turkey Day a few days off, today Apple publicly released FW version 4.2.1. As always, ultrasn0w unlockers please stay far far away from this official firmware. Wait for the ability to create custom 4.2.1. IPSWs that don’t update your baseband! If you’re not an unlocker, read on!
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. A tethered jailbreak means that each time your device loses battery power or needs to be rebooted, you must attach it to a PC or Mac to boot into the jailbroken state. @comex is working hard on a method that may untether the 4.2.1 jailbreak, but it will require you to have your 4.1 SHSH blobs in order to use it. No word on how much more effort it will take though (please don’t bug @comex about it!). (We also have an alternative method that may work, but @comex’s method is much more elegant.)
So when does all this 4.2.1 jailbreak action happen? Well if you’re a JB developer or tinkerer, you’ve already probably used the redsn0w mentioned in our last post to jailbreak 4.2.1 and at least get SSH working. But beyond that, there are still some last minute issues with MobileSubstrate and comex’s kernel patches that are being fixed. We’ll tweet and post a blog update when it’s all available (we hate to give ETAs, but barring any unforeseen problems, probably later today).
In the meantime, please make sure you have your 4.1 SHSH blobs for all your devices. These will be important even for firmware beyond 4.1 (using both comex’s method and our alternative, depending on how each of them turn out.)
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.

Unlockers please stay far far away from this official firmware – updating to iOS 4.2.1 will update your baseband to 5.15.04 (3G/3GS) and to 3.10.01 (iPhone 4), and it seems that there are no unlocks available yet.
due to geohot’s limera1n exploit, all recent devices can be jailbroken.
4.2.1 jailbreak is *tethered* on all of these recent devices.
ultrasn0w unlock – very soon; probably in the next 48 hours November 28! iPhone 4 with baseband 2.10.04 unlock – the Dev Team will need more time.
Stay tuned while we provide all the latest updates!
