    In fact, I think Apple would never force users to upgrade their bootloader to smth new (e.g. 4.x or 5.x or whatever) cause it's really dangerous for the phone. So, downgrading to bootloader 3.9 is just a good way to have ur iPhone working with newest FW. Also I assume Geohot's custom bootloader(if it'll be finally released) would be possible to upgrade to from both bootloaders.
    I'll wait for March 6th to see what happens and for now I'm 80% sure to downgrade my BL.

    yeah if the custom BL will come out you can still update to it via 3.9

    Apparently the bug in 4.6 that allows the Geohot unlock and the software BL downgrade is not present in 3.9. So I wouldn't automatically assume that changing from 3.9 to a custom BL by software methods will be possible. It would require quite a bit of additional hacking...

    Installing Cydia programs on a phone that has no internet connection: read this.

    Editing binary .plist, .strings, .nib and .xib files:
    * on your computer: Windows tool / conversion website.
    * on your iPhone: convert those files in a terminal with plutil (installed with Erica Utilities) or edit them with iFile (Cydia links).

    Sure it's like that. But there's at least even amount of people with BL3.9 & BL4.6, so it's a matter of time to have BL3.9 hacked that way(software upgrade).

    Another thing:
    BL3.9 allows patched secpacks from the same or newer basebands.
    BL4.6_GEOMOD allows everything.

    But what the difference if patched secpacks are released in few hours time after Apple's new firmware release?)))

    SoLor :

    I dl this file and extracted the first 0x20000 bytes.
    I compared that with winhex with the nor from the 3.9.

    There is big difference, many bytes at the end of the file from bl 4.6 marqued "FF" and at the end of the 3.9 there is many marqued "00"

    Can someone explain me this difference between the "00" and the "FF"

    Thanks

    yeah, i'm sure there will be a new bootloader by then. and i think it should be on the same day when iphone 1 was released.

    anyway today i downgraded my 4.6 to 3.9 (reluctantly), because nothing else seemed to solve the problem (restores and whatever else not working) and the only working solution was to downgrade. so i did it. it's working now, but i do not recommend it.
