Baseband Requirement on iOS 4.2.1!!

So pretty much if you are using Saurik’s server or tiny umbrella and if you are trying to restore 4.2.1 on an iPhone 4, you will end up in recovery mode and tiny umbrella will not be able to pull you out of recovery. This comes from BigBoss;

“It seems that Apple has decided to put a baseband requirement on iOS. So at this point, if you are using Saurik’s server or tiny umbrella and trying to restore 4.2.1 on an iPhone 4, you will end up in recovery mode and tiny umbrella will not be able to pull you out of recovery. In this case, you will have to restore 4.1 again or you will have to restore 4.2.1 stock and be tether jailbroken. (Of course, I recommend 4.1 and not bothering with 4.2.1 at all). If you are an unlocker, this is a no brainier. Do not update to 4.2.1 even to test it at this point.”

So there you have it do not update to iOS 4.2.1, especially if you are an unlocker! The jailbreak will be tethered/semitethered!

More Details On iOS 4.2.1 Jailbreak and Unlock

Im pretty sure you guys know that Apple released iOS 4.2.1 to the public and as always the dev team posted an update on there blog. Here’s what it says;

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 (and all 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.

So there you have it guys.. Don’t update to 4.2.1 if you want a tethered/semitethered jailbreak!

The long awaited sn0wbreeze 2.1 has been released by iH8sn0w. It supports all javascript:void(0)devices on all bootroms which includes iPod 4, Apple TV and iPhone 4 along with all the other devices!

1. Download iPSW and select it from Sn0wbreeze

2. Build iPSW and include extras if you want

iOS 4.2 Jailbreak/Unlock Update Status

Im sure you guys know that iOS 4.2 will be releasing soon (most likely friday) and there will be a jailbreak for it/unlock. Here is an update that the dev team gave on there blog:

• Thanks to geohot’s limera1n exploit, and our original pwnage2 exploit, and @pod2g’s ipod2g-MC exploit, absolutely all devices at all iOS firmware versions are capable of being jailbroken.
• The untethered jailbreak of those very latest FWs and latest devices depends on @comex hacks.  His hacks so far extend only to 4.1 and 4.2beta3.  He’s working on a way to extend it to 4.2 and beyond.  Just wait for him to work out his method.
• iPhone 3G and 3GS unlockers will be covered by our upcoming unlock.  Stay away from any updates to Apple FW until our official release and you’ll be okay.  Just stay away from all Apple IPSWs
• iPhone4 unlockers are not left out in the cold.  @sherif_hashim has found some very promising avenues to pursue.  Those will be explored as soon as possible after all the 4.2 madness.

What does this mean to you?

• If you’re an unlocker, just stay where you are.  Please, just stay where you are. Any mistakes you make now may be permanent.
• If you only care about the jailbreak and you’re absolutely sure you have your personalized 4.1 SHSH hashes, feel free to experiment but keep in mind that any mistakes you make may result in your losing pictures or notes or bookmarks that you’d rather keep.  Honestly unless you love living on the bleeding edge, it’s better to just wait for official updates from Cydia/redsn0w/PwnageTool.
• Don’t buy or donate to any unlock or jailbreak scammers.  Every legitimate solution you will find for unlocks or jailbreaks will be offered without an extended hand.  That’s how the iPhone jailbreak/unlock community has succeeded.  It’s about freedom to do what you want with your $300 device —  not about donations, egos, tweets, or “interviews.”

Be Sure to save your your SHSH blobs for iOS 4.2 Beta 3 because it will ensure an untethered jaibreak for the official iOS 4.2 jailbreak! Save it using tinyumbrella (link below and video guide below!)
