iPhone 3GS screenshot

Following the instructions shown in iClarified I have managed to perform a successful 3GS untethered jailbreak and unlock on Windows 7.
The thing is that my iPhone’s week number is 43, which is in the range 40-45 of the “unknown” behavior. I already have modem firmware 06.15.00 from a previous jailbreak/unlock.
So what I did was to follow exaclty the instructions shown here, with only one difference. At the step where you choose what options to select on redsn0w, I also activated the “Install iPad baseband” option.

Remember to perform a backup through the iTunes in order to save data and be able to restore after the process.

I am not 100% sure that you need all steps described in the original iClarified tutorial but here is what worked for me:

  1. Downloaded the latest redsn0w application.
  2. Downloaded the 5.0.1 iOS.
  3. Started redsn0w and selected “Extras”

  4. Pressed “Select IPSW” and selected the downloaded 5.0.1. iOS
  5. Since my iPhone’s week number is 43 as the next dialog box states results vary, I chose “Yes”, my iPhone is a newer (fixed) model.
  6. Then, at a final stage, I chose the options to “Install Cydia” and “Install iPad baseband”, otherwise I would have lost the possibility to unlock the device.
  7. After all these steps, things go as expected and described in the original iClarified tutorial.
  8. After the jailbreak succeeded and I got control of the iPhone, I had to follow the instructions regarding the unlocking process through Cydia and ultrasn0w.
  9. Had to reboot the device again in order for the unlock to actually work!

At the end I performed a restore through the iTunes and I got my device up and working great!
