    Cool, I hope the iOS 4.0 Jailbreak is only days away from being released. I got a new iPhone 3GS on 4.0 and wanna JB!!!!

    Thanx

    • ppuniversal 16 July 2010 at 1:22 am #

      i think you can still JB 3GS… just look around this website.

      • Whiplash 16 July 2010 at 1:54 am #

        thanx, but it ca only been done if it was JB before and u saved some file.

        Sadly it cant be done yet

      • Dhruv 16 July 2010 at 11:42 am #

  2. Amin 16 July 2010 at 1:23 am #

    4.0.1 is even wors than 4.0 on my 3GS

    • Brandon 16 July 2010 at 1:57 am #

      Are you retarded? If you would’ve read. It’s for the iPhone 4! Not 3GS. Yes it’ll work on 3GS… But it’s to fix reception on the new iPhone… Not 3GS…. Damn people are dumb.

      • Smitty 16 July 2010 at 10:30 am #

        Nope, the new firmware is for all iphone. According to Jobs, all the iphones display incorrect signal strength. Weather you believe it’s true or not is up to you.

        with regard to the following on top of this very page I do enjoy the tone of your post: “Apple has released the iOS 4.0.1 for iPhone 4, 3GS, 3G and iPod Touch 3G, 2G”. ROFL!

  3. mike S 16 July 2010 at 3:16 am #

    Yup, waiting for a jailbreak for the 3gs with iOS4 as well…

  4. erikve88 16 July 2010 at 7:38 am #

    can i unlock the 4.0.1 os yet or not and how about the os4

    • vodanhz 19 July 2010 at 11:32 am #

      i think so.

      MuscleNerd

      Obviously avoid today’s 4.0.1 update until JB tools are updated. Luckily, no baseband change so ultrasn0w lives on :) 5:48 AM Jul 16th via web

    “iOS 4.0.1 is released to fix the reception issue”

    You can’t fix a hardware fail with software. You can check in detail the proof of the obvious at

    • Smitty 16 July 2010 at 7:51 pm #

      I agree, it’s hardware problem and can’t be fixed on iPhone4. Just don’t hold your phone in a normal way or use duct tape like Consumer Reports recommends.

  6. congchuaso1 21 July 2010 at 7:19 am #

    just want to jail break iphone

  7. Smitty 23 July 2010 at 12:55 am #

    Anyone else experiencing issues with Ios4?
    Upgraded my 3GS to 4.0 a few weeks ago and occasionally the phone suddenly restarts and goes to apple logo for a long time, then finally homescreen appears.
    Also phone has called people on it’s own. Never had that happen before in the last 4 years owning iPhone.
    Wifi icon dosent always show when connected to wifi.
    The phone uses much more memory and can be slow at times.

    • tarekelmalah 24 July 2010 at 7:24 pm #

      i have 3gs ios4 and ive never had any problems with it since the day it came out and im the wifi all day long !
      u should try to restore ur iphone that should do the treat im guessing it did not install completely or correctly on ur iphone !

      • Smitty 27 July 2010 at 12:24 pm #

        Good to know it’s not IOS4. Love it except an occasioal glitch. Think you’re right that something went wrong on install, gonna reinstall. Thanks

  8. Ipad Touch 3 August 2010 at 2:55 pm #

    what is with my ipod touch isnt there an update ??
    only for iphone ???

    • Smitty 4 August 2010 at 2:59 am #

      What iPod model, and what firmware?
      Check this chart, you will find your answer at jailbreakmatrix.com

    I downloaded IOS 4.0.1 firmware from this site – how do I use this to upgrade my phone?
    My phone is currently running on 3.1.3 with spirit jailbreak.
    I saved shsh with Tiny Umbrella – it shows as 4.0.1.shsh – is that correct? I thought it would show as 3.1.3

    • Smitty 4 August 2010 at 12:59 am #

      There is no need to download this firmware. Upgrade to 4.0.1 from iTunes, then use jailbreakme.com or jailbreakme.modmyi.com to jailbreak from your iPhone. Then unlock with ultratrasn0w from cydia. Good luck.

  10. FLat 4 August 2010 at 1:55 am #

    Thanks for the reply Smitty. I already downloaded the ios 4. Do I have to download it through iTunes again or is there another way to install the already downloaded ios. I’m a little short on bandwidth and would prefer not downloading it again if at all possible.

    • Smitty 4 August 2010 at 2:51 am #

      I had some major issues with the iOS4 downloaded from above so can’t recommend using it. It’s always best to use the latest firmware, there are some bugs that were fixed. I think it would be worth the time to download the new 4.0.1 direct from iTunes, then jailbreakme.modmyi.com from iPhone browser.

      • FLat 4 August 2010 at 6:59 am #

        Thanks again Smitty, I’ll follow your recommendation

      • speed_manan 5 August 2010 at 12:48 am #

        hello smitty
        dear i upgraded my iphone 3gs as told by you,i used itunes to upgrade it to 4.0.1 from 3.1.3. Now i’m stuck at Emergency Call Screen! (I’m not blaming you :) ) i have a new bootrom 3Gs and i don’t have official carrier sim with me and i’m completely unaware about my official carrier! how can i by-pass it now? this happen when we upgrade the iphone using itunes..i have one more 3GS with me,same type,new bootrom etc but its on 3.1.3..can i upgrade it with some custom firmware so i don’t have to activate it afterwards,is it possible?

        kind regards

        • Smitty 5 August 2010 at 7:53 am #

          I’m sorry for your situation. Try this method using phonebook sim to hacktivate the phone. Hope it helps.

          • speed_manan 8 August 2010 at 1:50 am #

            well i did it like that. But now what i’m facing is even more strange, i don’t know why its doing like this now. I activated my phone using the PHONEBOOK sims,it got activated. Then,when i inserted my sim in it and unlocked it…a screen of emergency call is back saying A Different sim is detective,connect to itunes. And Itunes is again saying to insert official carrier sim. Again whole process again,but still when i insert my sim it goes back to activation.

            i hope you have some solution for this too.

            Kind Regards

        • Raven 7 August 2010 at 5:22 am #

            Hacktivation app is now available in cydia. Try this link: http://www.applei.ph/one/component/option,com_kunena/Itemid,49/func,view/catid,54/id,1073797507/

  11. garlicb1 10 August 2010 at 3:34 am #

    I used jailbreak 2.0 on Saturday and it worked fine on my 3gs 4.0.1. I came to work to help a coworker do the same and after we enter the jailbreakme.com url in safari and slide to jailbreak it just times out. Is this a problem with the load on the jailbreakme.com server or is there a problem with my coworker’s iPhone?

    Thanks in advance.

    • garlicb1 10 August 2010 at 8:21 pm #

      It must have been the server because he went home and tried it later in the evening and everything worked fine.

      Thanks for all the hard work.

  12. SteveT 13 August 2010 at 7:49 pm #

    Just a quick question, a work mate has updated to 4.0.2 and wants to drop back down to 4.0.1. He has downloaded the 4.0.1 firmware and done the whole shift+click restore but iTunes tells him he firmware is not compatible.

    I am assuming it’s too late for him to jump back down to 4.0.1? Is this because Apple is no longer signing 4.0.1?

  13. Larshara 16 August 2010 at 5:09 am #

    Hi,
    I’m pretty poor at anything technical and I’m trying to downgrade from the 4.0.2 to 4.0.1, but the 4.0.1 I have downloadedting to be restored in iTunes. What am I doing wrong?

  14. saad823 19 August 2010 at 2:50 am #
