How to jailbreak your CDMA iPhone 4S
Note that sometimes after the jailbreak process, some icons on your iPhone will appear differently or turn completely white. We don't know why this happens, and it doesn't always happen, but your apps will still function properly even if the icons change.
Open the Cydia app on your iPhone and wait for the Cydia to prepare filesystem. After it's finished, you might see a message to unlock your SIM card, but you can do that later. Open Cydia again select your user type. I suggest you select User here. Now click done. Cydia will begin downloading and installing packages. You must let this process finish before going on to the next step or you will receive errors.
