This video is for Users, who have problems with their WIFI on their Apple iPhone. We will see how to install Ultrasn0w on our devices without an Internet Connection.. We will be using DiskAid to access our iPhone Contents. iPhone used in this video was iPhone 3g running iOS4.

You can use whatever Client you use to access iPhone Contents, like iPhone Browser on Windows or Phone Disk on Mac.

You will be needing Ultrasn0w deb file. Download it here:
http://www.mediafire.com/?5ogil6h0ugbugu1

And if you need DiskAid Download it here for Mac & PC http://www.digidna.net/products/diskaid/download

IMPORTANT: In order to Unlock your iPhone 3g or 3gS on 4.1 or 4.2/4.2.1 you will first need to change its baseband. To change your iPhone's baseband you need to use Redsn0w 0.9.6b5 . This Redsn0w 0.9.6b5 will change your baseband to 6.15.00 and then you can Unlock. How to use Redsn0w 0.9.6b5 Video Link http://www.youtube.com/watch?v=yHCmV1GO5xI

When you have opened DiskAid then you need to transfer the *.deb files that you downloaded from Ultrasn0w zipped file, put them in var/root/Media/Cydia/AutoInstall. If the Cydia/AutoInstall directory is not there, then you create one as demonstrated in the video.

NOTE 1: Type Cydia folder with UpperCase "C" and AutoInstall folder with UpperCase 'A' and 'I".

Once all above is done as shown in the video, you need to restart your phone couple times, the 1st for Cydia to install the packages and second time Ultrasn0w start to work. Done.

NOTE 2: If you are stuck on Apple logo on second boot due to your own Tethered Jailbreak. Then use Redsn0w 0.9.6b6 to boot. Put iPhone in DFU mode and run redsnow with option 'just boot tethered right now'.

Enjoy and Feel free to ask.

  • Can you help me please. I have the wifi greyed out on my iphone 3G with 4.2.1 (8c148) and 5.15.04 baseband. I was following this video but got stuck in Diskaid. I cannot see any "Root" folder on the left. Please help.

  • @robertjan456 Inorder to Unlock first you need to do is change your baseband to 06.15.00 exactly as shown in the video. Then when you are at point where u have to use DiskAid , see on your left where it says 'File System'. Click on it. Now you will get 'Root'. Then go to var/root/media/Cydia/AutoInsta­ll. All details are in DiskAid video.
