How to Jailbreak iOS 5 On iPhone 4, 3GS, iPad, iPod touch 3G/ 4G Using RedSn0w

These are instructions on how to jailbreak your iPhone 4 on the 5.0 firmware using RedSn0w for Mac.
This procedure will cause you to upgrade your baseband potentially ruining your chances for an Unlock. Please wait until we have posted a tutorial on how to update to iOS 5 using a custom ipsw if you need an Unlock. The jailbreak is also tethered which means you will need to connect your device to the computer each time you reboot. Finally, it may be prudent to save your SHSH Blobs by following this tutorial before continuing.
If you want to jailbreak a lower firmware version you can find the appropriate tutorial here.
Step One
Create a folder on your desktop called Pwnage
Download RedSn0w 0.9.9b5 from here (If you are on Windows,download RedSn0w 0.9.9b4)and place it in the Pwnage folder. Likewise, download the 5.0 firmware from here and place it in the Pwnage folder. (Note: you do not need to download the 5.0 firmware if you are already on iOS 5.0)
Extract the RedSn0w zip file by double clicking it.
