Got yourself an iPhone 3G or 3GS that’s carrier-locked but want to unlock it to be able to use any SIM card with it? Ultrasn0w 0.93 is now available that lets you do just that, on almost all baseband versions on iPhone 3G or 3GS. For more information and the complete guide, read on after the jump.
Carriers locking devices to their own SIM cards isn’t an uncommon practice and still continues, to make you stick with them because your device will not operate with the SIM card of any other carrier. There are lots of scenarios when one might need to do it though. Whether you are simply tired of your old carrier and want to try a new one out, or you bought a used phone and found out it was locked, or got one as a gift, or are travelling abroad and want to use a local carrier there rather than paying huge roaming charges, the iPhone Dev-Team has you covered with the latest release of Ultrasn0w.
This new version of ultrasn0w 0.93 is now easily downloadable through Cydia and unlocks your iPhone 3G/3GS for following basebands:
- 04.26.08
- 05.11.07
- 05.12.01
- 05.13.04
As these are the baseband versions found on a majority of iPhone 3G and 3GS devices, this covers almost all devices out there, with perhaps a few odd exceptions. If you have your iPhone 3G or iPhone 3GS with any of the above mentioned basebands, just follow the step wise procedure listed below and you’ll unlock your phone in no time.
Requirements:
First of all, please do NOT continue if by any chance your baseband version does not match one of the four shown above.
In order to make iPhone 3G and iPhone 3GS ultrasn0w unlock work, you will be needing a jailbroken iPhone 3G or 3GS running iOS 4 so if you haven’t done it yet, jailbreak it now before proceeding. You can find instructions for it by searching AddictiveTips with your phone model, firmware version and baseband version.
Also, please make sure that before installation, you have your 3G network powered off especially if you are a T-Mobile subscriber.
Procedure:
- Start Cydia on your iPhone 3G /3GS and go to the ‘Manage’ tab.
- Tap ‘Sources’ and then tap ‘Edit’, followed by ‘Add’.
- Now type the following repo in the URL field : http://repo666.ultraSn0w.com
- Next, search for ultrasn0w 0.93 using Cydia search bar. Once located, install by tapping the ‘Install’ button on the top left corner of the display.
Once Ultrasn0w has installed successfuly, your iPhone 3G or 3GS has been unlocked, and you can now use it with a carrier of your choice just by changing the SIM card.
