How to Jailbreak iPhone 4/3GS 6.1.3 And Preserve Basebands With Sn0wbreeze v2.9.14

A few days ago, iH8sn0w released sn0wbreeze 2.9.14 for iOS 6.1.3 jailbreaking, Sn0wbreeze allows user to preserve an unlockable baseband on iOS 6.1.3, this is the Gevey SIM and UtraSn0w users want. With Sn0wbreeze they can creat a pre-jailbreak custom 6.1.3 Firmware, which added the old baseband. This is intended to unlock their iPhone again.


  • Sn0wbreeze 2.9.14 brings support for iOS 6.1.3, iOS 6.1.2, iOS 6.1, iOS 6.0.1 and 6.0.
  • You can only jailbreak A4 or older devices are supported on 6.1.3 that includes iPhone 4, iPod Touch 4G and iPhone 3GS.
  • It’s an tehtered jailbreak for aboved mentioned devices on 6.1.3, untethered on iOS 6.1.2.
  • NOT support iPhone 5, iPhone 4S, iPad 4/3/2, iPad mini or iPod Touch 5G. For these devices we recommend you to use evasi0n jailbreak:
  • You can only operate the following steps on the Windows platform, as sn0wbreeze is lonly available for Windows.
  • If your iPhone is with old bootrom you can perform untethered jailbreak using Simple Mode which dosen’t change baseband as well.

If your iPhone depends on UltraSn0w unlock or Gevey SIM, we recommend using Sn0wbreeze to jailbreak. Otherwise you’d better use evasi0n jailbreak instead.

    Hi Kevin,

    I found your tutorial really simple and well done. So far I only find those with the same as you did but using also redsnow.

    My case, I have an Iphone 4 GSM, version 4.3(8F190) Baseband 04.10.01 and so far I am happy with gevey card. I don´t want jailbreak.

    So just make me clear, with your tutorial I will be able to do this without Jailbreak isn´t it?

    Anyway, good job, Greetings..
