These are instructions on how to jailbreak your iPhone 3GS or iPhone 4 on iOS 5.0.1 without updating the baseband using RedSn0w for Windows. You may want to do this to preserve an unlock from a lower baseband version.

Please note this jailbreak is tethered for every device but the old bootrom iPhone 3GS which means you will need to connect your device to the computer each time you reboot. Also, it may be prudent to save your SHSH Blobs by following this tutorial before continuing if you haven't already.

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 0.9.9b9d or higher from here and place it in the Pwnage folder. Likewise, download the 5.0.1 firmware from here and place it in the Pwnage folder.

Extract the RedSn0w zip file by double clicking it.


Step Two
Launch the redsn0w application from the redsn0w folder we just extracted.


Step Three
Click to select Extras from the main menu.


Step Four
Click to select Custom IPSW from the Extras menu.


Step Five
Navigate to the Pwnage folder on your desktop and select the IPSW we downloaded then click Open.


If you are using the iPhone 3GS you may be asked to identify whether you are on a newer or older model.


Step Six
RedSn0w will now begin building a custom IPSW for you.




Step Seven
You'll be notified once RedSn0w has completed building your IPSW. Click the OK button.


Step Eight
Click the Pwned DFU button from the Extras menu.


Step Nine
Plug your iPhone into the computer and make sure its OFF then click the Next button


Step Ten
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.


Step Eleven
RedSn0w will run the LimeRa1n exploit.


Step Twelve
You'll then be notified that your iPhone is in Pwned DFU mode.


Step Thirteen
Launch iTunes by clicking its icon in your dock.


Step Fourteen
Select your device from the list on the left then under the Summary tab hold down the Shift key and click the Restore button.


Step Fifteen
You will then be asked to select your IPSW for restore. Navigate to the Pwnage folder on your desktop and select the IPSW that begins with NO_BB then click the Open button.


Step Sixteen
iTunes will now restore and jailbreak your device using the Custom IPSW.



JAILBREAK AND INSTALL CYDIA
Follow these instructions to jailbreak your device on the new iOS 5.0.1 firmware.
- iPhone 4
- iPhone 3GS


BOOT TETHERED
Once you have jailbroken you will need to rerun redsn0w to boot tethered.

Step One
From the main RedSn0w menu click the Extras button.


Step Two
Select Just boot from the Extras menu to just boot tethered.



UNLOCK:
If you have a supported baseband you can now install UltraSn0w to unlock your device. Instructions are here.
