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 the 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. Sadly, it’s a Windows only app so you can’t follow this guide on a Mac. This guide assumes that you’ve already jailbroken your iPhone 3G or 3GS. Follow our guide here to jailbreak your iPhone 3G and here for iPhone 3GS.
Here’s what to do:
- Download Cyder II
- Connect your iPhone to your computer and launch Cyder II app.
- 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://repo666.ultrasn0w.com
- Click the play button on the top left. This will download the list of packages from these repositories.
- Switch to the Packages tab and select http://apt.saurik.com/cydia-3.7 in the Source and System in Section. In the list of packages, find Mobile Substrate, right click it and select Download with dependencies.
- Similarly, select http://repo666.ultrasn0w.com in sources and do the same with ultrasn0w. Right click it and select download.
- Now switch to the downloads tab. Right click on each package and download it.
- Switch to the File Manager tab now. Drag and drop the packages from Cyder Cache to the Cydia Auto Install folder.
- Close Cyder.
- The packages will install when you restart your iPhone. You might have to restart the iPhone twice, as in my experience. After the second restart, your phone will find your carrier. Enjoy your unlocked iPhone!
