If you’ve got an iPhone 3G and have upgraded it to iOS 4, while jailbreaking the device has still been possible, you were out of luck so far when it comes to unlocking your phone. Luckily, that is no longer the case. The iPhone Dev Team has finally released Ultrasn0w 0.93 and with this tool, you can now unlock your jailbroken iPhone 3G running iOS 4 as well! We’ve got more details as well as the complete guide right here for you, so read on.
Carrier-locking of mobile phones to one particular service provider is just too restricting. While carriers do it to prevent you from switching to another one during your contract with them, there may be other valid reasons to do it too. At times, you might have run out of your talk time on your connection and might want to load a backup pre-paid SIM to use service. At other times, you may simply want to use another SIM to avail better rates in another state while travelling. And then there is international roaming; you may not want to pay hefty roaming charges when travelling abroad, when you can just insert a local SIM card into your phone and enjoy cheap local charges. These are some of the reasons why keeping a SIM-unlocked phone sucks even for those who want to stick to the same carrier primarily. And then there is always the case when you bought a used phone and need to unlock it to use with your carrier of choice.
So regardless of which of these is your reason, let’s get on with the unlocking part now. The method to unlock your phone with ultrasn0w is pretty simple and you will simply need to follow this guide to achieve the unlock.
If you are a T- Mobile subscriber, make sure to turn your 3G network off before installing Ultrasn0w 0.93.
- First, launch Cydia on your jailbroken iPhone 3G and navigate to “add source”.
- In the add source, type the following URL (without the quotation marks): “http://repo666.ultraSn0w.com”
- Now search for “ultrasn0w” using Cydia search and install by tapping “install” button located in the top-right corner of the screen.
- Let the installation complete and then you will have your iPhone 3G unlocked for any carrier SIM regardless of your geographical location.
Please note that this unlock is only applicable on jailbroken iPhone 3G for now. We are expecting a 3GS release soon but this ultrasn0w tool is not compatible with iPhone 3GS. This ultrasn0w 0.93 unlock tool is reported working for all baseband versions.
