One of the biggest reasons that I chose to stick with the tethered RedSn0w 0.9.6 release for my iPhone 4 is because of the beta version’s ongoing problems with Bluetooth support.

Up to this point, all of the beta versions of RedSn0w 0.9.7 — an untethered jailbreak released by the Dev Team — have thus far been devoid of Bluetooth capabilities. When using the beta, the Bluetooth option simply stated “Not Available.”

With the Dev Team’s latest update to the RedSnow beta, the Bluetooth hurdle has finally been eliminated, and now you can enjoy an untethered jailbreak with full Bluetooth support…

As with all versions of the RedSn0w 0.9.7 beta, you will need to have access to development 4.2b3 firmware in order to use this jailbreak. Unfortunately, there is only an OS X version of 0.9.7b5 thus far, and you can download it from our downloads section.

For your convenience, we have posted a full tutorial on jailbreaking your iPhone 4 running iOS 4.2.1 using the RedSn0w beta. Please keep in mind that this is still a beta jailbreak, meaning it is likely that you will still encounter bugs here and there.

One of the few big remaining bugs continues to be incompatibility with Skype; the app crashes as soon as you try to launch it. There are also reports of incompatibilities with iBooks.

Seeing as Skype is a heavily used app of mine, this is still a deal breaker for me. For those of you who are developers and don’t use Skype, RedSn0w 0.9.7b5 may be your ticket to untethered freedom.

What do you think? I’m still waiting it out…

  • EgoHot

    I can confirm Skype still crashes but iBooks seems to work fine for me. I’ve only tested this on my iPad. I wont update my iPhone 4 until I can preserve my unlockable baseband.

  • KJ

    So are Skype and maybe ibooks “only” items left to fix?? Or are there other problems?

  • msxy

    with beta 4 i can’t open cydia neather safari ??????? why?

    • Comex

      Were working on it

  • Zachary Hardy

    Someone please help me. Whenever I try to jailbreak with RedSnow it always says can not verify ipsw and I always downlOad the right one. I hav an iPhone 4 with 4.2.1 please help.

    • Bullet

      are you sure you’re not confusing the 4.2.1 ISPW with the 4.2b3 ISPW it took me weeks to realize that there is two ISPWs

  • Les

    Hi there on the 3G sending a text from contacts phone crashes also done the some when mutitasking. Thank u for the heard work

  • matthuntdaug

    Wasn’t this beta suppose to be windows friendly?

  • SoCoMagNuM

    im waiting for windows version that supports skype then ill jb. if only i hadnt swopped my disfuctional launch iPhone 4 id still be jailbroken at iOS4.0. i just got frustrated that i had an hardware issue that caused my phone to lockup in standby mode when the weather is cold. first it wasnt that bad being it was summer/fall time. wasnt as frequent but being that its cold all the time my phone would lock up multiple times of the day requiring a hard reset. very tedious epecially when i rely on it for an alarm or important phone calls.

    got it swopped for free at local apple store and it came stock at iOS4.2.1…so thats only reason im at 4.2.1. i didnt care for all the game center stuff they came out with or the camera functions they implemented. i used skype so this is a no go for me til they get it working again.

  • Comex

    Guys we are working ad hard as we can a windows version will be released tomorrow hopefully.

    • Robocom

      Will unlock for 03.10.01 be coming anytime soon.. ? Several people including me updated their baseband by mistake somehow πŸ™

      • Comex

        No it’s never being released. Oh well. I quit.

    • Matthuntdaug

      Sounds good to me! Hopefully after the Ducks win the BCS I’ll get trying out the windows version.

    • SoCoMagNuM

      Appreciate it comex. Ive been patient all this time. Ya gotta do wat ya gotta do even tho ya really dont gotta do it lol. Seriously tho do ya thing. Theres many people like myself that believe in patience not filling the internet with rapid whining trying to rush others cause of their impatience. Dont fret over it. Theres many people that appreciate your work as well as others in the jailbreak community that actually put forth effort and contributes to the community instead of begging and offering nothing.

    • Joe

      I just picked up an iPhone 4, it was preloaded with 4.2.1. Is there any way to jailbreak this tethered or untethered? Never had a chance to save my shsh blobs. Please let me know. Thank you

    • Ricardodelsidney

      Make your next computer a Mac instead of a Windows computer. My next computer will be a MacBook Pro instead of another Windows computer. I am switching sides!

      • GASPONE

        You can also look at the option of setting up a OSX VM (virtual machine), there is a VMware torrent out there, works great with vmware player. It will recognize devices over the virtual usb port.

  • Boyan

      • josh

      • Maestro

        I really hope he was not serious…if not it would be very much disaster… much as I understand that its not easy job for getting the JB done…there are 1000’s of people who are checking sites every day for the new jailbreakme for iphone 4.2.1 with 03.10.01.
        Thanks in advance comex et all and appreciate your hard work.

  • Cameron

    I do not have anything tangible to contribute, but I want to say thanks for all the hard work. So many complain, yet they do not pay a penny for your services. I for one am thankful.

  • Yuma

    I’m sorry to bother, but when I jailbroke using redsn0w 0.9.7b5 with the correct IPSWs, I repeatedly get errors saying “Waiting to send Jailbreak Monte files” after several tries. Please help. Thank you so much. Comex, what would we do without you. I am grateful for your hard work.

    • Gatorman

      • Yuma

    Hi, Mr. Comex I really appreciate your hard work…I have an Iphone 4 4.1 2.10.04 Bb, when I would be able to unlock it T-Mobile……Thank you and keep up the great work…

  • TheStandard

    Just signing up to be updated

  • This Guy

    Is there a E.T.A for beta 6 and will it fix skype + iBooks?
    Also once that is fixed wont that mean redsn0w beta 6 will be the final launch (except for windows)?

  • TheStandard

    Does anyone know why I’m unable to open Cydia and Safari after I jailbreak my iPad? I’ve tried it on both windows and Mac.

  • Glenn Archibald

    I just picked up an iPhone 4, it was preloaded with 4.2.1. Is there any way to jailbreak this untethered? I am not sure what an shsh blob is. My previous iPhone 4 was jailbroken using the DevTeam’s jailbreak for version 4.1, then the phone was destroyed and I had to replace it. Can I jailbreak untethered?

  • KraftWiz

    Comex, Thanks from India !!

  • SAINT1590

    Thanks a LOT “COMEX” !!!

  • Chris

    arhhhh google sites is down for the download anyone know where else to get this from

  • Steve

    I have my iPhone JB with redsn0w 0.9.6b4 tethered can I download this newest 7b5 and just re-run the jailbreak without losing anything or will it reset all my jailbreak settings and apps?

  • Marko

    Skype not working certainly a huge issue for me.

  • Kitty

    I got a brand new iphone 4 on 03.10.01 base band. I wouldn’t have any unlock problem. I tried to tethered JB it and it worked. But everytime I tried to install five icon dock it automatically installs mobile substrate also. After that it reboots, yet it stays @ the apple logo there forever. Had to hard restore the phone. Can someone let me know if mobile substrate is workable on 4.2.1??? I don’t mind tethered JB but want to make sure these apps works or not.

    Thanks to anyone who can give me some idea before the perfect jail break comes out.

    And much thanks to the team for all the hard work!!!

  • Ashehole

    Good job Comex, thanks for you and the devteams hard work.
