Use Ultrasn0w for iOS 6.1.3 Unlocking on iPhone 4, 3GS, 3G for Free

Factory AT&T iPhone Unlock

Time is passing by and we start to forget about free iPhone unlocking but there is hope to get it here using Ultrasn0w for iOS 6.1.3 unlock iPhone 4 and 3GS.

Before starting to write this article I made an research and got info that Ultrasn0w 1.2.8 could unlock iOS 6.1.3 but with preserved baseband running on 3GS, 3G and 4 models.

If you are that lucky guy, here I’ll show you how to unlock iPhone for free using the most popular jailbreak tweak.

Ultrasn0w tool was developed by iPhone Dev team with the contributing help of @sherif_hashim and @Oranav. This software unlock is the most popular among iPhone users from around the world.

Also you can try to unlock iPhone 3GS 05.16.08 with Ultrasn0w installing iPad baseband but this method is not for all iPhones.

ultrasn0w ios 6.1.3 unlock iphoneSupported Baseband for Ultrasn0w 1.2.8

iPhone 4

  • 01.59.00

iPhone 3GS

  • 04.26.08
  • 05.11.07
  • 05.13.01
  • 05.12.01
  • 06.15.00

Go to Settings – General – About – Modem Firmware and compare digits with shown above. Don’t worry if you don’t see your baseband in a list. Because there is a cheap IMEI unlocking method. You can use it to free iPhone from AT&T or find solution for other US and international carriers and forever forget about worries regarding losing unlock during baseband and iOS update.

I know that it is not for free but you will get it permanently with official confirmation from service provider and Apple.

If everything is fine be ready to the next step which is very important for iOS 6.1.3 unlocking with ultrasn0w as well. Only jailbreak can help you to perform this.

You may know that there isn’t untethered jailbreak for iOS 6.1.3 but there is a tethered with two working tools:

  1. Jailbreak iOS 6.1.3 with Redsn0w [0.9.15b3]
  2. iOS 6.1.3 Jailbreaking with Sn0wbreeze [2.9.14]

After you made it we could start.

  13. James says:

    Hi, i have jailbroken and unlocked my iphone 3gs (UK) but receive 'no signal'. It is updated to iOS 6.1.3 and on baseband 05.16.08 and i have installed Cydia and ran Ultrasn0w 1.2.8. I then turned it off and on and inserted my new sim (Belgian).

    Do i simply need to tether it (connect to computer and launch redsn0w) everytime i turn it on for the unlock to work?

    any help would be appreciated,

    Thanks
