  • How to Capture Your iPhone 3GS iBEC and iBSS on Mac
    This guide will help you to get some important iBEC and iBSS files for your iPhone 3GS which will be required for jailbreak once it is released.

    Things you Need:

    We recommned you to backup before following the steps.

    Follow the steps below to get the files:

    Step One:

    Click and Hold the Finder icon in the dock and select Go to Folder.. from the pop-up options.





    Step Two:

    Type "/Users/'your username'/Library/Caches/Cleanup At Startup" in the pop-up box and click the 'Go' button. (Remove '' part from 'your username'). This will open the 'Cleanup At Startup' folder in the Finder window. Leave this window open.





    Step Three:

    Create a new folder, 'MOST IMPORTANT FILES IN THE WORLD' in this example.



    Step Four:

    Open iTunes and connect your iPhone 3GS to the computer in DFU Mode. Select it from the list of devices in the left sidebar. Hold option and click Restore button. Navigate to the iPhone firmware you downloaded before, select it and click 'Open'.



    Your iPhone will now begin restoring to the 3.0 firmware. You will be warned that this will erase your phone. Click the 'Restore' button to continue.



    Step Five:

    When the restore is in progress check the "/Users/'your username'/Library/Caches/Cleanup At Startup" folder you opened before. A new folder will appear with a name similar to 'iPhone Temporary Files.noindex'. When the folder appears, select it, and press Command+c to copy it to the clipboard.



    Open the 'MOST IMPORTANT FILES IN THE WORLD' folder you made before and paste 'iPhone Temporary Files.noindex' there. This will make a copy of your unique iBEC and iBSS.



    Make sure you finish these steps before the restore is completed and you're done!

    All the credit for the technique goes to DevTeam

    P.S. Thanks to Melech518 for all the screenshots!

    UPDATE: If you have already obtained a USB Dump from Purplera1n.com, no need to follow the guide

    UPDATE 2: Seems that Purplera1n just gives iBSS so if you want iBEC as well (can't restore to totally stock 3.0 without it), follow this method as well.

      I am curious about this too. I did the ECID and purplera1n process... do I still need to do this ALSO? Or is this a new technique?

      This is the simple way to do all of the above. You do not need to do both DFU and Restore. When you use the restore option or the dfu option the same files are created in the "Cleanup At Startup" folder. This folder contains ALL of the files needed!

      No you do not need to do this according to some, but i think it is smart to do considering the Dev Team will be implementing this in their JB. Plus purplera1n will only give you the iBSS and no iBEC

      in an earlier post, i got my ECID dump, when my phone rebooted into regular mode by accident and connected to itunes in regular mode. it said a dialog of "waiting for activation", and i immediately unplugged it all nervous. Oddly though, the screen on itunes just showed me the registration screen.

      Yet, expecting the "plug-into-itunes" screen, instead i got the regular "slide to unlock" screen...with springboard and all, the service icon said "no service" obviously because of the stock ATT sim inside" so i left it in airplane mode.

      My question is...if i already have my ECID, AND i get the iBEC/iBSS dump, could i theoretically get the springboard after restore, or would i be stuck on the "slide for emergency" screen instead? Mind you, i'm a t-mobile customer, not AT&T

      I am a Tmo customer as well!
      It is safe to keep the phone plugged in. Nothing will happen. You will get right back to the springboard after the restore. The waiting to activate is just your itunes recognizing the ATT sim in the phone and unlocking the spring board.

      I didn't have the "Cleanup At Startup" folder so i create it and followed the instructions and I have the files.
      never heard of the "Cleanup At Startup folder" before.

      Ok, question........I was about to buy a 3GS but I did not win it big in Vegas. My question is should I buy a 3GS now or wait. I have the money but like most, I was gonna wait until the jailbreak was released before buying one. But with 3.1 FW approaching, or it appears that way, I was wondering if I should wait or just buy one this weekend. Thoughts??

      is it hidden ?
      Users/myusername/Library/Caches/Cleanup At Startup

      myusername should be the username on your computer
      Mine is Rosco's for example...

      Can this process be done on a crappy PC?
      If so, is it really that different?
      Thanks,
