    Default Guide-Downgrade you 4.6 bootloader to 3.9 via software method
    Hi, firstly i'd like to say i did not make this guide i am just letting you all know about it, and please read all the warnings, i accept no responsibility for anything that goes wrong.

    You can now downgrade you bootloader to 3.9 from 4.6 using just a software method. If you are wondering why you would want to do this well it means you can run full 1.1.3 unlocked, by this i means 1.1.3 with 4.03.13G baseband unlocked. Also the 3.9 bootloader seems easier to unlock than the new 4.9 so you have better chance of an unlock being available and being available quickly, for furture firmware updates.

    Now here is the guide:

    Hope this helps some of you, i haven't seen it on the forums, sorry if someone else has posted this already,
