Here is the guide on the usage of the Sn0wbreeze 2.2:

Step 1: Download the Sn0wbreeze software.

Step 2. Download stock iOS 4.2.1 FW.

Step 3: Connect your iOS device to the system.

Step 4: Now launch the Sn0wbreeze and you will see a splash screen. Just skip this screen  by pressing the blue arrow at the bottom.

Step 5: Now it will prompt you to select the iOS 4.2.1 FW that you have downloaded in the Step 2. Now browse and select that.

Step 6: Now it will present you with a choice either to choose a Simple or an Expert mode. Choose the Expert mode here and continue.

Step 7: Now there is an opportunity to customize the FW. So just click on the General and on the blue arrow to continue to the next screen.

Step 8: Now on the screen that appears you have a choice of installing a number of tweaks such as animated bootlogos, openSSH installation, native backgrounding support, user wallpaper and battery percentage etc. After you are done press the blue arrow to continue.

Step 9: Now Sn0wbreeze will create the custom FW based on the choices that you made. It takes some time such as 5 to 10 minutes depending upon the computer speed. You don’t need to do anything here.

Step 10: Now firmware is ready but you need to put your device in DFU mode. Follow the on screen instructions to do so.

Step 11: Now launch the iTunes and it will tell you that it found a device in recovery mode. Press ok.

Step 12: Now in the iTunes hold down the Shift key and press the Restore button and iTunes will initiate the installation process for the custom FW that you have just cooked. It will take some time – wait for this.

Step 13: Now finally you are DONE!
