    i have just bought a new ipod touch in korea, it seems exactly the same but when i go to settings to find my baseband it is simply not there, i am interested in jailbreaking it but not sure if im compatible, any help?

    • iPhoneHeat 23 February 2010 at 2:27 pm #

      baseband is available in iPhone only because it’s responsible for making calls.
      which model do you have?
      and what firmware?

      • sean 23 March 2011 at 8:53 am #

        4.1 version

    • PaRanoID 2 November 2010 at 11:01 pm #

      Hey Just jailbreak it!
      You don’t hav to worry for baseband on iPod touches! :)

    • dncj015 17 December 2010 at 3:40 pm #

      Also, if you bought in Korea, you probably got a bootleg anyway… lol

      • Stixdee 16 July 2010 at 10:56 am #

        What time frame are we looking at, how long do we have to wait for the jailbreak? Just an estimate and why is the 3GS the only one unbreakable?

          hopefully soon.. Dev is finalizing the tool :)

    Hi,

    I am a newbie and just received my iphone 3GS 16GB IOS 4.0 AT&T locked. I am very confused with all the research I have done.

    Can someone guide me in simple steps how to unlock my phone?

    My requirement is simple, I just want to use my iphone with Vodafone carrier in India. I have a valid itunes/app store id ( I also have a ipod touch) and I want to continue buying apps from app store and also sync to my existing itunes 9.2 that I currently use to sync my ipod to.

    I will really appreciate help with simple steps starting from opening the iphone box.

    Thanks a ton in advance.

    • iPhoneHeat 29 July 2010 at 12:28 am #

    Is there a way to jailbreak Iphone 3GS with IOS 4 that hasn’t been previously jailbroken ??

    Base band – 05.13.04
    Version 4.0 (8A293)
    Old bootloader – IBOOT – 359.3

    Thanks in advance

    • GbackMania 1 August 2010 at 12:22 am #

      and unlock it …

    • iPhoneHeat 1 August 2010 at 12:12 pm #

      wait for the Comex’s jailbreak

      • Stixdee 8 August 2010 at 5:47 pm #

        First Activate with an AT&T Sim Card then on the iPhone Safari, go to jailbreakme.com on Wifi then wait till the iphone is jailbroken then go to Cydia and unlock there. shortcut is to just google “How to jailbreak iPhone 3gs 4.0″ you will get the answers.

    I have a Iphone 3gs jailbroken unlocked firmware: 5.12.01 version 3.1.3 (7E18) and I am thinking about updating to iOS 4.01.
    Question 1 – do you suggest it?
    Question 2 – what are the step by step instructions to jailbrake and unlock after upgrade.
    Thank you,

  12. cflow33 16 August 2010 at 6:06 am #

    Alright…
    I am wanting to jailbreak and unlock an iPhone 3G running 4.0.1.
    It is not yet setup via iTunes, as I am about to sell it to a customer.

    I did the jailbreakme.com and thought I was ready to unlock it,
    and then realized, after so much reading prior to jailbreaking,
    that iOS 4.0.1 cannot be unlocked.

    So now I am trying to:
    1) Figure out a way to unlock it as 4.0.1, or
    2) Restore back into iOS 4.0 and then re-jailbreak it and THEN FINALLY unlock it.

    Any help would be appreciated!

    Thanx
    Cflow

    I have the iPhone 4 and just updated to OS 4.1 a couple of days ago. Few ?’s… 1. If I jailbreak this thing, will still be able to use the itunes apps that I purchased? 2. does the jailbreak world keep up with stuff like the video calls. 3. Will I be able to jailbreak this latest version 4.1 (Modem Firmware 02.10.04). I’ve been a iphone user since Feb 09 but NEVER considered jailbreaking until now. Thank you for helping me as I’m scared as heck for doing this but don’t want to be limited.

          Hey, Don’t worry.. If u feel Your jailbreak is the reason for call blocks, restore with your itunes. Your phone will revert back to old conditions (Hope you didnt change your base band for jailbreaking – coz if u had done that, restoring wont be possible)

          After restore check, if it works well.. Then jailbreak it again properly. Hope this would help u

    How can i unlock it ? Which software i can use to unlock it ?

  40. sajal 15 October 2011 at 6:04 pm #

    Hi,

    I had purchased a jailbroken and unlocked iphone around 6 months back. The iOS on that is 4.0.1 woth Modem Firmware as 01.40.52 . I am planning to upgrade the iOS to 4.3.3 as some of the apps that I want to run are supported by this version and I found a lot of help on net that teaches about how u can jailbreak and unlock ur phone with this iOS version . But all talk about preserving the baseband to 01.59.00 . Now am not sure how I can get the baseband 01.59.00 before I start the jailbreak/unlock process.

    Is there smthg like if I upgrade the iOS from 4.0.1 to 4.3.3 the Firmware will automatically get upgraded from 01.40.52 to 01.59.00 ?

    I am in India and using my phone that I purchased from US. Though my mobile carrier now provides the iPhone 4 and supports it, I am still not sure If I will be able to use there sim on my phone as I purchased it from US and got it unlocked and jailbroken there.

    Please provide me insight if I am doing the right thg by planning to upgrade the iOS? I jus don’t want that once I upgrade I am not able to use my iphone with my mobile connection if it gets locked again.

    Thanks in Advance.

    Regards,
    Sajal

      I’m now in India and using Gevey Turbo but I would really like to unlock it.

      If you are any wiser about how to do with the least damage please please let me know! I’m gathering information but I don’t know which websites to trust.
