    Can anyone shed light on my question PLEASE.

    Ok, so i'm downloading ios 4.0.2 now and it says it will take about 2 hours. Whatever. Here is my question.

    When 4.0.1 came out, I downloaded it with my iphone 4. It took about 30 minutes to download. then it updated and all was good.


    I unplugged it, and grabbed my iphone 3GS (business) and plugged it in. Clicked update. all of the sudden i see the "downloading" playlist thing with a 1 next to it. I said, wtf??? I clicked on it, and surely enought, it's DOWNLOADING 4.0.1 again.

    Why did it do this? Shouldn't it already be downloaded and just go on my other phone?

    Please help guys.

    I thought once you download it, it will be in a folder in your library, and kept there. so when you need to restore or update older phones, it will use that firmware.

    Please help.

    Thank you

    The iPhone 4 and iPhone 3GS are two different devices running two different version of iOS 4.

    Every generation of iPhone and iPod Touch needs a different version of the firmware. It's like having a 2002 Ford Mustang and a 2011 Mustang. They both need engines (firmware) but there are small differences between the two that prevent them form being exactly the same.
