These are instructions on how to untether your jailbreak of iOS 4.2.1 using the iPhone Dev-Team's 'backup plan' method on Mac OS X.

Currently this beta is limited to iPhone4, iPad, and iPod touch 4G. Bluetooth functionality is disabled for the time being until some issues are resolved.

Requirements:
You will need to have access to the iOS 4.2b3 ipsw and your iOS 4.2b3 SHSH blobs saved. You also already need to be jailbroken on iOS 4.2.1. MAKE SURE YOU BACKUP BEFORE ATTEMPTING THIS AS IT IS A BETA!

Step One
Create a folder called Pwnage on your desktop and in it place:
-
- iOS 4.2.1 ([url=https://www.iclarified.com/750/where-to-download-iphone-firmware-files-from new=true]iPhone, iPad, iPod touch)
- iOS 4.2b3 *Only iPhone developers have legit access to this firmware

Step Two
Double click the RedSn0w archive to extract it. Then launch RedSn0w from the extracted folder.

Step Three
Click the Browse button

Select the iOS 4.2.1 ipsw from the Pwnage folder on your Desktop and click Open.

Click the Next button to continue.

RedSn0w will now prepare the jailbreak data.

You will now be presented with a list of checkboxes.

Select Jailbreak Monte (untether) from the list of checkboxes. You will be asked to select the iOS 4.2b3 ipsw from the Pwnage folder on your desktop then click Open. Click Next to continue.

Please plug your iPhone into the computer and make sure its OFF then click the Next button

RedSn0w will now guide you through the steps to get into DFU mode. You can find more help with DFU mode here

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 prepare Jailbreak Monte files, exploit with Limera1n, Upload RAM Disk and Kernel, and Send Jailbreak Monte files.

RedSn0w will inform you when it has completed successfully.

After hanging up a phone call froze badly needed a hard restart, said fcuk it went back to stock 4.2.1 makes me wanna buy apps now, nooooo

I appreciate what they do codeinsring that its free, but I'm fine at 4.1 for now. Why's there always a big rush for the Dev team and Geo hot to jailbreak the next firmware? Unless you just bought a new device and can't unlock its not that big of a deal. I mean Apple makes new enhancements and adds more functionality, but nothing that groundbreaking from one release to the next, at least nothing that makes me so impatient that I blog on the net complaining about not get the latest jailbreak from guys who do this entirely for free, thats just crazy. I am a little impatient for an unlock, but since tmobile changed their unlimited data plan to 200mbs I don't really care any more.

My iPad gets to the pineapple screen where it says, Installing Bundles, and hangs there. I think its some trouble with usbmuxd because I get this line in the Terminal > File "/Users/kenny/Desktop/Pwnage/usbmuxd-1.0.6/python-client/usbmux.py", line 111, in getpacket raise MuxVersionError("Version mismatch: expected %d, got %d"%(self.VERSION,version)) MuxVersionError: Version mismatch: expected 0, got 1 Anybody know what I'm doing wrong? Any help would be appreciated.
