How to Unlock Your iPhone 3GS OS 3.0 With UltraSn0w

Advertisements

These are instructions on how to software unlock the iPhone 3GS with OS 3.0 for use with any GSM cell phone carrier. Before you can follow these instructions you must have a jailbroken iPhone if you haven’t jailbreaked your iPhone 3G then follow our Guide Guide to Jailbreak your iPhone 3GS with Purplera1n For unlocking your iPhone UltraSn0w, a soft unlock payload from iPhone Dev Team is using. UltraSn0w is a small daemon that is launched on boot.  It injects the payload at boot and also whenever there is a baseband reset.  You won’t notice anything about it other than that your third-party sim now works. Once you have a Jailbreaked iPhone then you can use these easy steps to Unlock your iPhone.

Before getting started make sure your iPhone is jailbreaked with PurpleRa1n and Cydia is installed on your iPhone. The procedure and repo of Ultrasn0w is same as iPhone 3G.

Disclaimer : I am not responsible for any damage during the jailbreak and unlock process. Planetbeing already demonstrated  iPhone 3GS Unlock With Ultrasn0w Successful. Also Purplera1n is in beta form and there are some bugs. T mobile users make sure to turn off 3G in settings before applying Ultrasn0w. 80% results are positive but most of them complaints about no WiFi. So if you prefer unlock over WiFi only then use this guide.

    Hey,
    I’ve got an iPhone 3G 16GB running Version3.0 but I’ve done all the above steps using cydia and ultrasnow but after rebooting and entering a sim I get an activation screen which says this may take a few moments. I don’t understand why and also after turning the airplane mode on and off I get no bars of signal or recognised network. How do I overcome this and get the iPhone working please? Thanks guy.

    Does anyone know what the today released 0.8 Version of ultrasn0w changes? Is it safe to install? I have it as an update in Cydia and don’t know if i should install it. Because everything works now on my 3GS…

      @ iUsr if your phone is running well then you don’t have any need to re Ultrasn0w your phone again.
