Thread: what is baseband and bootloader?

  1. #1
    Default what is baseband and bootloader?
    News question I know but what exactly is the baseband? And what is the bootloader and how can I tell what version I have? And is the bootloader downgradeable?

    Thanks, Jason

    The bootloader is a piece of code burned into a chip that essentially starts the other parts of the phone - it cannot be downgraded by software.

    The baseband is what handles the comms on the iPhone - phone, wi-fi, bluetooth.

    The simplest way to check your versions is with BBInfo from the Installer (assuming you have access to the installer?). Otherwise, post the first 5 digits of your phone's serial number and somebody here will be able to tell you.

    you have a week 52 iphone, so most likely you have 1.1.2 firmware with a 4.6 bootloader that has a baseband of 04.02.13g. hope that answers your questions...

    yours is definitely 1.1.3 with a 4.6 bootloader and running 04.03.13g baseband. as of now there is no way to unlock your baseband version, but you can downgrade your firmware and jailbreak it.

    I think you should have bootloader 3.9 with baseband 04.01.13_G - hackable using AnySIM.

    4.6 bootloader, 04.02.13_G baseband - now hackable via GeoHot's gunlock script.
