How to unlock iPhone iOS 4.0 & 4.0.1, 4.2.1, 4.2without WIFI

Cyder II is a Cydia package manager which lets youconnect 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.

• Download Cyder II (from here)
• 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.Index of /cydia-3.7/ and 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 Index of /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 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
• 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
