Unlock Your iPhone 3GS for free - Use on any network Vodafone, Orange, O2 and 3 Three UK

As you may have seen from blog posts my iPhone 3GS is with Vodafone UK but doesn't always get the signal I need so I wanted to be able to use alternative SIMs in the iPhone if no signal exists at the location I am at.

There are various websites that offer iPhone 3GS unlocking for around the £20 - £25 mark but I spotted this video on YouTube that allows you to unlock your iPhone 3GS for free.

Once you have jailbroken your iPhone 3GS then you can load the ultrasn0w package which then unlocks the iPhone. Using Cydia add the URL

Once rebooted your iphone will be unlocked for free!

I've just tried it with my iPhone 3GS locked to Vodafone UK and it now works with SIMs from 3 and Orange so I can now use my iPhone 3GS on any network.


  1. So is this a permanent unlock? I have just had my iphone 3gs unlocked from Orange, but was told that if I updated the software it would revert to being locked. So will this solve that problem? Sorry I am new to all this.

    1. Unlock through carrier is permanent, no matter how often you upgrade/restore the iPhone.
      Software-unlock (ultrasn0w) will be lost with firmware update/upgrade/restore.
