    Actually if you update the firmware to 1.1.2, it is not supposed to change the bootloader. This means if your iphone came out initially with bootloader 3.9, it would stay at bootloader 3.9 and not becoming BL 4.6 even if you have upgraded to firmware 1.1.2.
    The question is: was your phone really have the bl 3.9 when you purchased?
    I doubted it though, since your iphone generation was the 42nd week and it was more likely to have bl 4.6 from the OTB.
    Anyway, if you have doubt about it, why don't you try to read the forum thread about upgrading from 1.1.1 to fw 1.1.2 with bootloader 3.9.
    check it out.
