    Hi,

    For one reason or another after downloading the 2.0.1 firmware through safari and safari decompressing the zip it made i am left with a folder called iPhone1,2 which is about 250mb big
    This folder contains 3 .dmgs a firmware folder a .plist file and a file thats called kernelcahe....(something or other).

    As i do not have the original file safari downloaded and can't redownload (im out in the sticks on dialup) does anyone know how i can compress the folders ive got into a .ipsw.

    I've tried archiving my main folder then changing the extension and i've tried making a dmg and changing the extension(didnt pursue all routes with this though).

    If anyone knows what i should do to get a .ipsw out of my folders then please let me know, or if someone could at least post the folders contained in the .ipsw (show package contents) then id know if im going seriously wrong here.

    Thanks for the help (and hello to the forum! has been a godsend for finding quality information so far!)

    Will

    Did you check in your Trash to see if the original .ipsw file is there ?
    PS: You should disable Safari's "open safe files after downloading" in the Preferences.

    Failing that, just compress the contents of the folder, not the folder itself, meaning, select everything in the folder and compress. Then change the .zip extension to .ipsw.

    You can't recompress the file it will corrupt it as far as I am aware!

    You will have to download it again - or even better - attatch your iPhone to itunes and click on restore and then let itunes download it!

    Just disconnect the phone so it does not restore when it has finished downloading!
