    Default What does the BL do?
    http://windows-mobiles.com/?p=249 Just ran a story saying ZiPhone voids the warranty by changing the BL. So my question is what does it do and is it upgradable?

    Have you searched this site? It's quite long winded, and there is already a thread on this.

    Anything you do against Apple's wishes voids your warranty. Ziphone will only downgrade your bootloader if you tell it to (RTFM). Currently bootloader 4.6 can't be unlocked so if your iPhone is a 4.6 OTB, it has to be downgraded to 3.9 so it can be unlocked.

    Ziphone will downgrade to 3.9 if you click on the "Do It All" option. And currently once this is done, it can't be reversed.

    iPlus does the same thing except uses a FB3.9 (fakeback) to downgrade, and this can be reversed. If need be.
    Get "iPod & iTunes for Dummies", it'll change your life.

    Yes I have searched, but only found was people asking with zero simple explanation

    But can someone answer this question: If I bought an iPhone in July 2007 and came with 3.9BL will it always be 3.9 or will firmware update it to 4.6?
