This step-by-step guide and tutorial will show you how to unlock your iPhone 3GS running OS 3.1 using UltraSn0w. This is a very simple method that requires only a few steps.
Step 1: You have to jailbreak your iPhone 3GS by following one of these tutorials.
Step 2: Once jailbroken, follow these steps:
- Launch Cydia.
- Add the following source to Cydia repo666.ultrasn0w.com (note there is a “0″ in sn0w, not an “o”).
- After installing this source in Cydia, search for “ultraSn0w”.
- Install UltraSn0w and reboot your iPhone.
Tha’ts as simple as that!

this tutorial is very misleading… i hate it. why don’t you clarify it is for base band 4.x only ?
WARNING!
THIS IS FOR BASEBAND 4.X ONLY..
THE OP IS A DOUCHEBAG AND DIDNT MENTION IT OUT!
SO IF YOU HAVE 5.X YOU ARE THE LOSER..
I used your tutorial to jailbreak my 3GS – 3.1 iPhone with BlackRa1n after a long wait. The jailbreak went very smoothly. I am having issues with the unlock. I followed all the steps and installed ultrasn0w, but when I put in a SIM card it keeps searching for a network and then finally displays “No Service”, I do not get the Invalid SIM message. Could you please guide me further, am I missing something?
I have bought this phone new from a reseller so I am not aware how the previous owner upgraded to 3.1 Will upgrading to 3.1.2 help with the unlock process?
Thanks for your help!
I updated my baseband to 05.11. I’m just waiting for the new unlock.
I’m LOST i used the pwnage 3.1.4 and now i have the Modem Firmware 5.x.x
Now what??? tell me what i can do rom now on? just wait like a loser ???
I’m out of the country. My Iphone can’t directly connect to the internet. How can i unlock it with no internet connection?
hi, the jailbreak worked perfectly, whoever the unlock was unsuccessfull. i have Modem Firmware 05.11.07 and i did all the steps mentioned in this tutorial, but i got “Locked SIM” when i put SIM in the iphone after installing ultrasn0w…
