Step 7) – Once RedSn0w has finished preparing your iPhone for the Jailbreak you will be asked you to specify options to go along with your Jailbreak. The only option that you actually need to make sure is checked is the Install Cydia option. Once you have ensured this option is checked, and any other options you may want, click the Next button.

Step 8 ) – After you have specified your Jailbreak options you can click the next button and RedSn0w 0.9.10b8b will begin Jailbreaking your iPhone. DO NOT interrupt or use the computer during this time. When your iPhone is finished being Jailbroken it will boot up with the Apple logo and not go any further. This is because you have a tethered Jailbreak and you will need to put your iPhone back in DFU mode and use RedSn0w 0.9.10b8b to boot it back into a functional and Jailbroken state.

Step 9) – As explained previously when you Jailbreak your iPhone tethered you will need to plug it into your computer every time your iPhone loses power to regain all functionality. Thus, to reboot your iPhone into a functional and Jailbroken state you will need to launch RedSn0w again, click the Extras Button > then click the Just boot button and you will simply need to put your iPhone into DFU mode again.
