The Dev Team has released their Redsn0w beta, dubbed Redsn0w 0.9.7b1 for iOS 4.2. We wanted to alert our readers, and at the same time provide a word of caution about the beta release.

To quote the Dev Team “This is a beta tester program. It’s not a general release!  Things can go very wrong, so please don’t even consider testing if you have pictures or other media on your device that you haven’t backed up!”

For that reason we recommend you hold off until the official release, especially if you rely on an ultrasn0w carrier unlock

Here are more details surrounding the beta release of Redsn0w:

  • This is a Mac only beta, unfortunately Windows users will have to be patient.
  • It’s only for the iPhone 4, or the iPad or iPod Touch 4G
  • Cydia must have your 4.2b3 SHSH blobs saved on file
  • You must have usbmuxd software installed on your Mac.

Known Bugs:

  • Bluetooth is disabled
  • iPod player doesn’t work on the iPhone 4 or the iPad
  • Application switcher will cause a crash

Those three bugs alone are likely deal breakers for most of all of you, and those are just the known issues. That, coupled with the fact that it’s still in beta, and not general release, is the reason why we recommend you all to hold off, and be patient.

You can download RedSn0w 0.9.7b1 from our downloads section. We’ll get a tutorial up in the next few hours.

Let the Dev Team do their thing, and we’re sure they’ll have a great public release in the very near future.

Are you going to wait it out?

  • Oh yes , I can wait for them …

    I have iPhone 3GS with iOS 4.2.1. I jailbreaked and unlocked it but I need to boot as tethered mode only. Can I boot untethered ?

    Btw, I used the redsnow 0.9.6b5 and it upgraded to baseband 06.15 (iPad) to make this happen. I know there are limitations upgrading to 06.15 baseband, but I had no other option.

    Any help would be appreciated.

    Hello everybody,
    I want to jailbreak my iPhone4 iOS 4.2.1.
    It is unlock iPhone from vocative provider.
    How can I jailbreak it?
    Help me please!!

    • Burki

      I dont know?

  • Fahim

    Still waiting for the full version 4.2.1 to come

  • Shane Graham

    I am just wondering since they have been talking about an untethered release for a while if this has actually been released and I am just not aware of it. My guess is I am not that lucky but thought I would ask….it couldn’t hurt. This tethered JB is really a pain in the ass. I wouldn’t know how bad had I not already had one that wasn’t. It also seems to have less ability to work with more of the apps or tweaks so it has springboard crashed a lot.
    I would still recommend it, but cautiously if you are patent and truly see the value in having the other apps and freedom of a JBen phone. When the new release that isn’t BETA comes out where should we look for the news to hit first?

  • Shreksta12

    There isn’t going to be a jailbreak

  • Shreksta12

    There isn’t going to be a jailbreak
    It’s been put off for ages

  • Benaam

    I am awaiting for the 4.2.1 untethered JB release… saw few videos on YT, but I am pretty sure they are fake videos.

    One more thing, I have 3GS w/ iOS 4.2.1 can I downgrade to 4.1 (I don’t have the SHSH files for it) Also, can I use somebody’s SHSH blob to downgrade my iPhone ?

    Am really stuck up with this beast.. hope I cud have taken Blackberry or an Android Phone.

    Thanks for help in advance.
