A lot of users still don’t have access to WiFi. Plus many people, including me, have faced the random death of WiFi on their iPhone 3G recently. While the easiest way to unlock iOS 4 after jailbreak is to fire up Cydia, download and install ultrasn0w and reboot. There’s yet another simple method to do so, without WiFi, using Cyder II.

Cyder II is a Cydia package manager which lets you connect to your  iPhone 3G/3GS and download, install and backup packages and sources using your computer.  This guide assumes that you’ve already jailbroken your iPhone 3G or 3GS. Follow our guide here to jailbreak your iPhone.

Here’s what to do:

  1. Download Cyder II
  2. Connect your iPhone to your computer and launch Cyder II app.
  3. Add the following repositories in sources by right click anywhere in the field and clicking Add.

http://apt.saurik.com/cydia-3.7  and http://cydia.hotlink24h.com/

You will consider why I add http://cydia.hotlink24h.com/ instead of http://repo666.ultrasn0w.com/.

Just because now we can’t now get ultrasn0w 1.2. So I got it manually and add to my server. ( I know this may hurt Dev-Team, but I have to help Unlockers without Wifi can Unlock their devices).

4.  Download with Dependencies, so you will get mobilesubstrate 0.9.3367-1, too.

5. In tab “Downloads”, you will download Two files.

6. Drag these two files to Cydia AutoInstall and restart you iPhone. It’ll be free for you.

Notion:

If you’re on MAC, then you can download ultrans0w directly from our cydia to install.

Use this tool to transfer ultrasn0w and mobilesubstrate to /private/var/root/Media/Cydia/AutoInstall, then reboot you device.

iPhone Explorer lets you use an iPhone, iPod Touch or iPad as if it were in disk mode or a flash drive. iPhone Explorer is an iPhone browser for Mac & PC that lets you browse the files and folders on your iPhone as if it were a normal USB flash drive or pen drive. You can use the easy drag-and-drop methods to add or remove files and folders from the iPhone. Compatible with all iPhones and iPod Touches including the new iPhone 4 and iOS 4 firmware.

Download iPhone Explorer

you can download ultrans0w here:
[wp-like-locker]Ultrasn0w 1.2
mobilesubstrate 0.9.3367-1[/wp-like-locker]

Updated:

Ultrasn0w fixed uploaded and available to download now. It is compatible with iOS 4.3.1 and fixes the signal bar.

Update 12/11/2012:  The latest Ultrasn0w 1.2.7

Notice: If you’re on windows 7/ Windows 8 (64bit) with iTunes 11.x, you may get some missing files while running cyder II. You better copy the whole cyder II to C:\Program Files (x86)\Common Files\Apple\Apple Application Support

Then you can run it without any problem.

  2. i have iphone 3g software 4.1 bb 5.14 and wifi is working… i just can see on cydia ultrasn0w version 1.1, i cant see the new version, what can i do?! please help

  3. When i get to the part where i need to download with dependencies, ultrasn0w does not show up. The mobile substrate does, but there is nothing at all under the http://cydia.hotlink24h.com packages. Also on my phone Cydia is just a grey app, not like the usual brown with the white box. Please help!!!!

    • @iphone user: This for Unlockers who can’t connect to wifi can use cyder II to install ultrasn0w. Did you get error with cydia now?

  4. thank you very very very much, you just solved a problem I’ve been researching all day. thank you very very much

  5. I installed ultrasn0w 1.2 using cyder II for my iphone 3g with ios 4.1. but the signal stays at searching… after i restart.. . i tried it a few times again but it still keeps on doing that. I even tried jailbreaking it again using redsnow 0.9.6b4.. nothing worked out. please help me out.

    • @aMpReUL: Open cydia and check if ultrasn0w 1.2 and mobileSub were installed or not?. You just can use redsn0w 0.9.6beta5 only. redsnow 0.9.6b4 doesn’t work out for you. And Make sure your BB is 06.15.00

  9. Hey guys, I have done what you said, and my Iphone is stil locked. I’m using Iphone 3G, iOS 4.1 and BB 06.15.00. I have installed and ultrasn0w 1.2. After restarting my Iphone, it’s “Searching…” the network. After 5 minutes handset is restarting automaticly, and after 10 minutes it’s writing: SIM Failure,Invalid SIM… I change another SIM, and the same is happening. I suppose that ultrasn0w is trying to do its job, but without success.
    NB: ultrasn0w I installed via cyder II, this this link : http://www.hotlink24h.com/2010/11/how-to-unlock-iphone-3g3gs-using-ultrasn0w-1-2-without-wifi-with-cyder-ii/

    Could you please help me to unlock my iphone???

    Thank You

    • @yurraa: make sure you find ultrasn0w and mobilesub 1.2 in cydia. Did you jailbreak with the newest redsn0w?

  10. Yes, I jailbreak iPhone with the last redsnow version 0.9.6b5 . I remarked that in Cydia I have only ultrasnow 1.2 , I didn’t find mobilesub in cydia. I tried several times to put ultrasn0w and mobilesub in Iphone using Cyder 2 and iPhoneBrowser (iPhoneExplorer isn’t rworking on my PC (win xp) as you wrote “transfer ultrasn0w and mobilesubstrate to /private/var/root/Media/Cydia/AutoInstall, then reboot you device” and no result.

    Can you please suggest another options?

  11. dude this is really cool job yar,i just got frustrated after upgrading first.thank u very much….keep going……cheers…

  12. Perfect instructions. Read carefully. And remember – no need to open Cydia after copying to Autoinstall and rebooting iPhone. As I rebooted with my simcard in, the unlock was instantaneous! :)
    TY TY TY

  14. I’ve tried to do this now on cyder but when i enter the http://cydia.hotlink24h.com URL, a big exclamation mark comes next to it and when i click on the play button it tells me “Cant resolve URL” in that little information box at the bottom of the screen. Please help.

  15. I am a mac user. I followed the instructions above with iphone explorer but cannot find the /private/var/root/Media/Cydia/AutoInstall path.

    The only path I find is root/private/var/root/Media but I don’t see Cydia/AutoInstall inside. Cydia is already installed on my iphone 3G. Any help?

  16. Hi,
    I have a 3g 4.2.1 on 5.15.04 fw. The phone is jailbroken but I have no wifi so I can’t unlock it.. I want to use Cyder 2, but I have no idea which ultrasnow I need to download?
    Any help would be great.

      • Thanks for replying!
        I’ve tried to unlock using this guide, and no luck. on the part I have to copy Cydia and Mobilesubstrate to Cydia Autoinstall, nothing happens. I noticed it says on the bottom “iphone/ipod connection error” I assume this means I have to use the iPad FW, like you said. Can you please help me with the sources? I have no idea which sources to add, or which packages to download :(

  18. Hi, I’m a mac user. on iPhone explorer i cant find the autoinstall folder (root/private/var/root/Media) but there is no Cydia/AutoInstall dir, Do I need to create those folders and put UltraSn0w and mobile substrate?

    i have cydia installed
    [iPhone 3G 4.2.1 06.15.00]

  19. Hey I have 3g 4.2 with 6.15.00 and I followed exactly how you said but I’m still not getting any wifi networks. Has some thing been to fix this issue yet because it seems many others have the same issue. I can make and recieve calls, just no wifi :(

        I unlock my iPhone 3G with redsn0w and after that it doesn’t see any wifi networks. So I can’t install ultrasn0w. If i follow this guide, will it fix the wifi problem?

  24. You are the best!!! Mine was iPhone 3G and I cannot install ultrasn0w from Cydia. Keep up the good work and please continue helping people out with their tech problems!

  25. Hi there!
    I have a jailbroken 3g iphone, 4.2.1 with BB 06.15 and it’s unable to see any wifi network, so I’ve tried your method (the one for Mac) for uploading ultrasn0w onto Cydia, and once I reboot, the phone just enters the never-ending reboot cycle. Do you have any advice on how to stop this? Am I doing something wrong?

    • @nataliya there is something wrong. Have u installed the latest ultrasn0w? Just try to restore your iPhone.

      • I tried to do a custom restore (which worked) and then install ultrasn0w 1.2, but this problem just keeps on persisting. Once I try to reboot after moving ultrasn0w and mobilesubstrate to /private/var/root/Media/Cydia/AutoInstall, the phone just keeps on hanging in the reboot mode.

  26. Hats off to you to help me unlocking my Iphone 3G without a wifi. By the way, I am having very poor network through Iphone. SIM works fine with other phones. I have to be at certain places to get the network. People who try to call me often faces connection problems. Any suggestions please?

  27. I have completed all of the mentioned above steps and I get nothing. I have an iPhone 3g with 4.2.1 and BB 6.15. I used redsn0w 0.96B5 to jailbreak and then doing your method to install the apps. i also took the deb files and used iFunBox to install them and they do not appear in my software installed list.

    Why?

    • Well I found another package that had Ultrasnow and Mobile SUbstrate and I was able to get mobile substrate installed but I still cant get my iPhone to take Ultrasnow 1.2 or 1.2.1. Any ideas?

  28. oh man! ur the best i m searchng ths from past 4 days i was no wifi i find ur cmnt oh man ur awsum to me love u muah muah muah muah muah realy u did it for me wow man wow love u yar muah
