    Hi,

    Been reading some sites saying backing up of ibec and ibss files are needed after 3.0 JB. But i'm confused, is it for the 3Gs or 3G ?

    I'm using 3G. (windows)

    thanks.

    As far as I know it is all phones that run the 3.0 software and may be interested in upgrading to future OS updates such as 3.1 once it becomes available. In other words, it has to do with the OS you are running and not the model of phone.

    Don't upgrade when 3.1 comes out until the jailbreakers say its ok.

    I think these files are required by the iphone when upgrading software. So, if a future 3.1 comes out, and the nice hacker guys modify the software (e.g. to avoid upgrading the baseband so unlocks still work), the iphone will need to see these two files before allowing the software onto it. This is my guess of how it all works anyway.

    Trouble is, you can only get these files by restoring to the most up-to-date firmware. So, when Apple releases 3.1 (which will be soon) you will have to restore to that firmware to get these files. However, restoring to 3.1 might ruin your chances of a jailbreak or unlock.

    So, the moral of this story is: get these files while you still can, while 3.0 is still the most up-to-date software.

    Better to get now and not need than to wait and not be able to get them. You can get them both at the same time by using the IBEC and IBSS Grabber during a DFU restore.

    I jailbroke my phone a few days after buying it and didn’t know the need to capture these two files.

    I’m hoping I can still capture these but need to confirm on the steps necessary to avoid losing all my data/apps/settings.

    What is the best way to do this? I was thinking of the following

    Install the backup app from cydia and backup according to the instructions
    Backup phone in itunes
    DFU, capture the two files
    Restore in itunes
    Re-jailbreak
    Restore app

    Is this correct? anything particular i need to do during restore in itunes so that i can restore my phone back to the way it is today?

    thanks

    Why cant someone post the ibec and ibss files up here? Do you only need to back them up if you unlock your iPhone?

    Use the IBSS IBEC Grabber program and follow the txt file instructions. Once it is running, put your iPhone if full DFU mode and it will grab both files. Make sure you're not in "soft" DFU mode.

    I did this a couple of weeks ago and grabbed both files on the first try.
