will apple change the bootloader with 1.1.4?

IF they do, then it wont affect 1.1.3 or below, as the bootloader is not changed with a firmware upgrade...
Most likely no. Because the SDK is around the corner, furthermore a bootloader takes time (lots of it) to be correctly written, compiled and tested.
Also, since Apple & Infineon had a perfect not software ulockable bootloader untill 2 weeks ago, Apple & Infineon is probably in pre-pre-Alpha stage of the next Bootloader. Apple & Infineon took from July to November to introduce the Bootloader 4.6, and 4 month time span. Most likely around 3.5 months we are going to see a new bootloader.
So a new bootloader next firmware? Highly unlikely, impossible no.
Bootloader does not take a long time to compile and make.
3.9 BL from June to week 42 = 4 month
4.6 BL week 42 to end of feb. = 4 month
These are just bootloader revisions not writing a totally different bootloader from scratch. They're writing the bootloader from an existing foundation that needs to address the basic needs of the phone (tying baseband, firmware, and phone hardware together) this will not be changed. However, the interactions, validation, tokens, checking activated versus unactivated, are just added features (extra codes on top of the CORE code that BOOTLOADER NEEDS to function properly) 3.9 to 4.6 = 7 iterations of revise withing 4 month. That's almost like 2 revisions a month, with each revision addressing issues that apple wishes to patch, loopholes, and new functionality.
they can come out with bootloader 4.7 with 1 or 2 issues patched withing 2 weeks if they wanted to.
Since it's almost another 4 month almost another 16-18 weeks passed. i would imaging they'd have at least 5-8 iterations done to address the issues they need before they release the SDK, patching vulnerability, and still maintain that core function.
I would say if apple condone hackers they won't release a new bootloader, but if they want to send out a message to ban hacking.. i'm pretty sure they'll release a new bootloader along with the SDK. (see what happened to tinycode). that's a good antihack message on where apple stands.
Hey, sorry... I am not up on all this...
The Baseband is what "runs" the radio, right? Would that be cellular, Wifi, BT, or all?
And what exactly IS Bootloader? From the name, it sounds like just the bare bones OS to get the "real" OS loaded and running, sort of like BIOS on a PC. Is that right? If so, it would not seem to need much of an update... so I MUST be missing something!

Yeah you have the idea.
But more precisely, it is the first program to start-up when your turn your iPhone 'on'. Also its the thing that puts your iPhone into DFU (Restore Mode) and the same thing that let's you update your iPhone.
If the bootloader is written to prevent anything added, it can invalidate the firmware, prevent modifications and/or prevent anything to be added to it; hence, the problems with unlocking OTB's 1.1.2 and 1.1.3 early in December and Novemober.
If you screw up your bootloader you end up with a PERMANENT brick.
They don't upgrade the bootloader on existing 4.6 handsets though do they? New bootloaders only appear on new handsets right?
