Unlock iPhone 3G/3GS iOS 4 With Ultrasn0w 0.93

By Ali Waqas on Jun 22 2010 24 Comments

Now with iOS 4 officially announced, you can easily jailbreak and unlock this firmware on your iPhone 3G and 3GS (all basebands). We are not so sure about unlocks working on 3GS and iPod touch 3G because a tweet from @musclenerd went like: iPhone 3GS & iPod 3G owners who used Spirit for your first Jailbreak show stay away from iOS4 for now.

So this is the step by step guide on how to unlock you iPhone 3G and 3GS using UltraSn0w 0.93.

For this unlock, you need to have a jailbroken iPhone 3G/ 3GS.

  1. The first step is to go to Manage tab in Cydia and add the following source “http://repo666.ultraSn0w.com”.
  2. If you are a T –Mobile subscriber, make sure to turn off your 3G network before installing ultrasn0w 0.93.
  3. Search for Ultrasnow 0.93 and press Install at the top end of the screen.
  4. After installation, you will see that your iPhone 3G and 3GS has been unlocked.

You can also unlock your iPhone 3G using Redsn0w 0.9 Beta 5 as per details posted here.

Update: Ultrasnow 0.93 is compatible with all basebands since iOS 3.0, they include, 04.26.08, 05.11.07, 05.12.01, and 05.13.04, as mentioned here.

Disclaimer: Please make sure that you have ample hands-on jailbreaking experience before trying your hands on this one. Addictivetips won’t be liable for any damages that may incur to your device during the process

    Does any one know if I can jail break my iPhone 3G running firmware 3.1.3 and baseband 5.12.0.1. Looks like for using this unlock, you need a phone that was at least jailbroken earlier.

    Can some one please help??!

      Hi there Yes it work all baseband I just jailbreak my using spirit just one click just go to spiritjb.com and dowload a free jailbreak make sure u backup all ur apps music on ur iphone and follow step by step or u can pay just 9.99 for http://www.latestiphoneunlock.com

      U can also use ultrasn0w version 0.93 to unlock for any sim card I done it with my own on a 5.12.01 3.1.3 5.9 work best fast and fun. keep in mind if u don’t have iphone 4 u may want to keep the 3.1.3 because it slow for iphone 3g 3rd gen not all apps will work on the ios4 I keep my iphone 3.1.3 for me use Cydia and Rock Your phone to make background it the best way for iphone 3rd gen

    Hi,
    I am using an unlocked iPhone 3G with baseband 05.11.07 and firmware 3.1. I want to upgrade to OS4.0. So, please help me how to do it?

  • Aiden

    Thanks worked like a charm 3g 16gb iso4 tmobile

  • Jared

    Many thanks – have been waiting for this for months!

  • Elvlaprena

    I bought an Iphone 3G on ebay not realizing these difficulties. It is linked to AT&T with OS 4.1 and Firmware 5.12.01 – I noticed several people asked about 4 but will these work with 4.1 as well? I have T-Mobile so my other question would be whether I could do this with a prepaid AT&T card as it seems I would need to at least have it actively online to do this, is that correct and if so would a prepaid sim work? Thank you soooo much in advance and please feel free to email me if you need any further info. to answer this.

  • stackbundles

    so i have a iphone 3g with the 4.1 update would these steps unlock my phone so i can put my t-mobile sim card in it.?
