(adsbygoogle = window.adsbygoogle || []).push({}); So I have a 3GS on OS4, I am using Windows. What, if anything, is available to me?

I have searched but dont really understand it too much.

Can I downgrade to 3.1.3 and jailbreak using Spirit? If so how?

Or is there a working Jailbreak available to me?

+Rep for a good answer

Right, imagining you have a windows os i would suggest downgrading it to 3.1.3. The main reason for this is that i would think everything from cydia works on 3.1.3 and nothing really works on iOS4.

Downgrading

BEFORE YOU DOWNGRADE SYNC YOUR 3GS JUST SO IF ANYTHING C*CKS UP YOU HAVE IT BACKED UP :y:

• To downgrade your device Garf, get the firmware you want from You must login or register to view this content. (you want 3.1.3) also make sure it downloads with the ending of ".ipsw" and not ".zip". If it downloads with .zip before you click save just re-name the end to .ipsw
  
  
• Once you have downloaded the firmware, you need to open iTunes and make your your iPhone is connected to your PC via usb.
  
  
• Once iTunes detects you 3gs go to the restore button but DON'T click it. Hold the 'Shift' button then click restore and a box should pop up.
  
  
• When the box pops up, go to you desktop and locate the firmware. Double click it then it should start to restore your 3gs.
  
  
• Once its restored you should be on 3.1.3. It will say what firmware your on by looking You must login or register to view this content.. Once your on 3.1.3 the jailbreak is simple just download Spirt from You must login or register to view this content..
  
  
• Once you have downloaded spirit, just make sure you iPhone is still connected and open the program. After you open spirit it will recognize the device you have and the firmware. Just press the jailbreak button and its that simple.

If you have any questions just Pm me

I get to this stage

When the box pops up, go to you desktop and locate the firmware. Double click it then it should start to restore your 3gs

Halfway through I get a error message and it stops. Im using windows 7, dont know if that makes any difference.

Do you know if you have a New Bootrom? AKA: New boot?

do you get error 1015 or somethig...if so, i may be able to help

hmmm.... the only thing i could suggest is putting your device into DFU mode then shift-restoring it that way. However i dont know if this will 100% fix the error. If you want to go ahead with this then just post here garf and ill post a Tut .

So yes I will take that TUT please

EDIT

Both buttons for 7 seconds then the middle button for 10 seconds, phone went into recovery mode, did the shift restore and got the same error.

2ND EDIT

1) First navigate to “c:\windows\system32\drivers\etc\” and open the ‘hosts’ file in notepad. To do so, right click on the file and select Open With->Notepad. At the end of the document, add this string “74.208.10.249 gs.apple.com”.

(Run notepad as administrator first then navigate through notepad otherwise you cant save the string.)

2) Now connect your iPhone to iTunes in recovery mode. To do so, first switch off your device. Then press the Home button on your handset and connect the USB cable. As soon as you connect the USB cable, the device will boot up and a “Connect To iTunes” screen will be displayed. Users can now stop pressing the Home button.

3) Fire up iTunes now. You will see your iPhone/iPod Touch detected in recovery mode. Now, whilst pressing the Shift key for Windows users or Alt key on the Mac platform, click on the Restore option.

Now just select the original OS 3.1.3 and voila, you are done. Now you can again enjoy OS 3.1.3 on your iTouch device.
