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 to Jailbreak iPhone 3G OS 3.0 With RedSn0w on Windows Mac 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.

  9. Rashed September 11, 2009 Reply

    I have the same problem,

    whenever i go to cydia – manage – edit – and try to add http://repo666.ultrasn0w.com (both with a zero and ‘/’) a message appears saying “did not find repository….etc”.

    i have updated to OS 3.0, jailbroken with redsnow v.08, selected “Install Cydia” only, restored backups, rebooted my iphone 3G numerous times..

    i dont have any carriers signals, the no service message is constant.

    Please, can some one provide a solution to this… ive searched all over the net and couldnt retrieve any info.

    Moreover, i tried browsing the repo on the net but that doesnt work either. Is the link actually down? or is there someother issue that needs to be looked into? all i can say is that my jailbreak and update were fine.

    please help.

    hi vinay!!!

    I’m trying to unlock my 3G but when I’m at step 7 it shows ” did not find repository” and even says to contact with author of cydia??? can u please help me out!!!???

    Your tutorial are excellent.

    I used the one to jailbreak using redsn0w and it worked flowlessly.

    When I decided to dive and unlock the phone I was a little bit worry about leaving the sim card in or taking it out while installing ultrasn0w. The gudie is not clear on that sense.

    I decided to leave it on against the advice given by Vinay to take it out between steps 1-15.

    The installation gives you the option to boot up the device, therefore steps 14 and 15 are kind of redunctant.
    After all my phone boot up fine. It took a little bit longer to boot up, but it came out fine.

    I will test my phone with other cariers tomorrow.

    Thanks for all the hard work.

    Hi, thank you soooo much!!!!
    I finally could unlock and previously jailbreak with the other tutorial provided in this website, my iphone 3g!!!

    I had found other tutorials, but this one has excellent visual aid.

    Some remarks:
    -I connected the usb in the port behind the cpu. I had tried to jailbreak the iphone using the one in the front, but I just made a big mess (maybe it isn’t as secure as the one in the back, it kept connecting and disconnecting).
    -Also, I now know that it’s very important to create the folder with the downloads in it. Other tutorials didn’t specify this and it was another mess…

    Well, that’s all I can say about my experience. Thanx again for such wonderful help!!!

    Hello guys. I have a 3G with OS 2.2 and I´d like to upgrade it. Itunes offers 3.0.1. I have no AT&T SIM card. Looking for others comments I don´t understand if I can do all steps without any SIM inserted up to use Cydia to install UltraSn0w. Can I?
    Thanks

    Hi everyone!

    I have iphone 3g but my stupid device can not detect any wireless network even the wifi setting is turned on.

    My iphone 3g is locked and right now i don’t have any legit sim card.

    Any other ways so i can preinstalled the ultrasn0w to unlock my device without using wifi when jailbreaking?

    Or anyone knows how to fix the wifi detection?

    Thanks in advance!

    @ ChrisC
    As far as I know, you don’t need to unlock the phone if you plan to use it on O2 UK in the UK! Coz O2 is Apple’s chosen carrier here!

    Now I have a jailbreak iphone 3g 3.0.1 following your steps, but the option WiFi disappear, now is in Grey color, so I don’t have internet signal to unlock my iphone, I reviewed a lot on internet about this problem, and nobody know how fix this. I tried everything, reset, restore, clean all history, network, absolutely all recommendations, even call to apple and nothing. Some help please?, I’m not At&t customer so they can’t help me changing the phone, before jailbreak it was working good for three months with my friend At&t account, he upgrade to 3gS and sold me this one, like new, just three months of use. So, no more WiFi? oh, and the battery now drain very, very, very fast.

    Hi,

    I’ve been trying to unlock for 5 hours now and this is where I have got to…

    - Attempted Jailbreak using both Pwnage Tool (mac) and redsn0w
    - Added ultrasn0w to cydia repository, installed.
    - T-mobile sim card seems to work with full signal strength and activates in iTunes
    - when i insert my o2 sim (i need to use this one) it has no signal and gives me the Restricted Network – Your selected cellular network is restricted. message.

    Any ideas how I can get this working on o2 uk??

    Thanks

    A question…After unlocking the iphone, you can use any SIM card on it, right? But if you travel to other countries, the GSM network band might be different than what’s here in the U.S. (i.e. 850 vs. 900 vs. 1900). Does the unlocked iphone automatically switches to the right network? I don’t seem to be able to change the network band in the phone. Please help!

    Thanks

      @Lee iPhone is a Quad Band GSM phone so no matters where ever you go in the world your Ultrasn0wed phone will work for you..

  33. Hasabnia June 25, 2009 Reply

    When I first open Cydia it asks me who I am. What should I click on? User, Hacker or Developer? I tried using the User one. But evertime I try to add the source it says “Installed by Package” instead of saying “Entered by user”, why is that? And how can I change it? After I try putting in the source it tells me that it “Did not find repository”. How can i fix that?

  34. Eddie June 25, 2009 Reply

    Vinay, you missed my question. I know you will need to unlock before making a call with another carrier. What I was trying to ask was, can I get through the whole unlocking procedure without an AT&T sim card?

    Your Step Fifteen stated “You should now be able to insert the SIM of your choice!”, my question is, do you require an AT&T sim between step 1 and step 15? Can the SIM card slot be empty?

    • Vinay June 25, 2009 Reply

      @ Eddie Don’t leave any sim in between step 1 to 15

  35. Eddie June 25, 2009 Reply

    Got a stupid question, if I have a AT&T locked phone, and I do not have an at&t sim card. I know from my iPhone 2G’s experience, after restoring to OS3.0, I won’t be able to access anything other than emergency call. After redsn0wing the iphone 3G, would I be able to use cydia without an AT&T sim card?

    • Vinay June 25, 2009 Reply

      @ Eddie Yes unlocking is meant for running unofficial SIM cards. In the case of iPhone 3G you can Jailbreak with Redsn0w and for unlocking you have to install Ultrasn0w. After jailbreaking you’ll be able to run Cydia and other Apps but for making calls you have to unlock your iPhone.
