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 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.

Hey, I have my iPhone 4 GSM on 4.3.5 with Gevey, I want to put it on 5.0 (without jailbreak) but I can't do it like in the tutorial. iTunes gives me the "not ilegible" message or anther 1XXX error. I've tried downloading from different sources, using Tinyumbrella, different versions of RedSn0w, updating iTunes from 10.5.0 to 10.5.1... everything but I just can't. Any suggestions?

Use tinyumbrella and uncheck "Set hosts to Cydia on exit."

I upgraded to IOS 5.0 keeping my baseband 0f 4.10.? and unlocked using Redsn0w. I downloaded a program from Cydia. When installing, the phone never turned back on. It got stuck with the Apple logo on. I attempted to use TinyUmbrella to get it out of restore state. That didn't work, so I tried to restore in iTunes using the custom ispw that I had previously upgraded to 5.O on. I received an error message (1600) that my phone could not be restored. I attempted to jailbreak and install Cydia again. It went through all the steps and said it was done, but I am stuck with a black screen with a bunch of steps ending on :Applem2ScalerCSCDriver:Added framebuffer device: AppleCLCD id: c7da5000 with the curser on the next line. How can I get my phone working again?
