  • iOS 4.2 Jailbreak Status Update

    With the release of Firmware version 4.2.1, rises the concern of jailbreaking and unlock compatibility. If your waiting for an unlock, wait for the ability to create custom 4.2.1 firmwares. If you’re not an unlocker, then there is good news for jailbreaking your devices.

    Those of you who own an iPhone3G, older iPhone3GS, and non-MC iPod touch 2G will benefit the most with this news from the Dev-Team. They explain that due to a combination of the original pwnage2 exploit, the arm7_go exploit, 24kpwn, and limera1n, your device is “just as jailbreakable as ever.”

    For those of you with the newer devices, geohot’s limera1n exploit, will actually work just fine. The unfortunate news is that, as of right now, the 4.2.1 jailbreak is *tethered* on new devices. What is a tethered jailbreak? "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, the guy behind creating tether hacks, is working hard as usual on an untethered 4.2.1 jailbreak, but unfortunately at this point, it will require you to have your 4.1 SHSH blobs in order to use it.

    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).
    As usual, it is important to make sure you have your 4.1 SHSH blobs for all your devices saved at least via Cydia. It's going to start to be even more important to make sure your SHSH blobs get saved as new firmwares come 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.

      Whhhhhhyyyyyyyy dOnT they mention the iPad in their updates!?!?!?! I don't see how it's any less relevant being as how unlocks are not being mentioned and the features,excitement, and anticipation for 4.2 on any other device is just "meh" iPad is the only one getting an overhaul and NO ONE has yet given official word on wether to update or not, or wether the iPad is exempt from the iffiness.

      Further, with the shoe stringy and sketchy jb method for iPad mentioned on redmondpie and the cydia patch available... Can we use that sketchy method and later upgrade to the official jailbreak and "new" cydia later or will we have screwed the pooch?

      I for one don't do $h*t until a dev tells me it's Okay because I don't have the money or resources to replace my device or deal with the unusability because all of my apple is used for work.

      I love you fellas for all you do but hey.... Show some love to the teeny tiny iPad modding community!

      Go Comex go!

      -Now, if someone could walk me through the SHSH blob scenario real quick I'd really appreciate it. I have SHSH saved in Cydia and locally with Umbrella for 4.0.1 . I use 4.1 and I just tried to save again and it said 4.0.1 SHSH's are saved. So, after Comex does his magic (which the dev team says will require 4.1 SHSH blobs), will older 4.0.1 SHSH blobs work? Also, how the heck does Umbrella work? Is it even needed if Cydia has your blobs saved?

      You can jailbreak with jailbreakme 2.0 at 4.0.1

      You can unlock at 4.1 if you preserve your baseband below 4.1, the baseband itself at 4.1 cannot be unlocked.

      well from what i understand is the new devices all have new bootroms or A4 chips right? The tethered jailbreak? Which would include the iPad. So if thats right then peepz with iPads can Jailbreak to 4.2.1 but it will be a tethered JB until a newer hack by @comex is released.

      With 4.1 shsh blogs saved, your jailbreak at 4.2.1 will be tethered jailbreak.

      Then you will have to get home, use a computer to boot up your iphone.

      Is there a thread that has a list of app compatibility for 4.2.1? (I imagine most work, but since Cydia stopped working due the update, others could have issues.)

      If it is factory unlocked, you can use any sim even without even jailbreaking it unless your iphone is software unlock.

      Baaaaaaahhhhhhhhhhh. Why the f r there postings about how to jailbreak, unlock or learn about 4.0 4.0.1 4.1 etc? Why are there How To questions at all? Ask yes or no questions, opinion questions, make comments or opinions, even ask advice, but you think anyone is going to create a step by step guide in THIS post?

      This is the place we vent our frustrations, not a place to teach. Trust me, I ask 10000000's of questions, this isn't the place to expect answers.

      Feel free to ***** though, we do lots of that

      Again, anyone more familiar with SHSH blobs know if saved 4.01 blobs should work for the 4.2.1 untethered jb (when it's released of course)?
