Hold down both the Home button and the Power button for 10 seconds.
Release the Power button and continue holding the Home button until RedSn0w detects the device.

RedSn0w will then begin fetch the SHSH blobs from your device and submit them to Cydia.
Once this is complete you will be notified that your submission was a success. Click the Back button to return to RedSn0w.
Click the SHSH blobs button and then click the Query button to make sure Cydia has your blobs saved.

RedSn0w also saves your blobs in a plist located within the RedSn0w folder. We would recommend keeping these for added safety.
