Baseband Version? What's the diff? - XPERIA X10 Q&A, Help & Troubleshooting

Seems like there are 2 baseband versions out on 2.1 for our X10's....version 2.0.46 and the newer 2.0.49.
What exactly does it control or do?
I have been playing around with certain flashes and I have been able to install the original 2.1 upgrade (.504) with the newest baseband.
Firmware Version 2.1-update1
Baseband Version: 2.0.49 (<--Originally was 2.0.46)
Kernel Version: 2.6.29
Builld-Number: 2.0.A.0.504
Is there any advantage to this? I have read on other subforums here on XDA that the basebands control battery life as well as other stuff. Since some are saying that the newest X10 firmware (2.0.2.A.024) has better battery life, will the above configuration improve it over the original 2.1 firmware?

BTW.....running original 2.1 firmware with the updated baseband, I am still able to root using the traditional methods (superclick and zroot).

Hey, how were you able to do this? did you just flash the .sin files without installing the update.zip? (I'm guessing you used zdzihu's update method)
I tried updating the rom and I had some issues getting the system to mount as r/w and then the xrecovery menu would stop working, are you having these issues?

That would work too. What I did was take the system.sin file from the X10a .504 upgrade (original 2.1 firmware) and used all other .sin files from the newer X10a 2.1 update. Used x10 flasher to flash my phone and got the above combo.

Now Baseband 2.1.54 is official via SE Update Service - people are grabbing it for Multitouch, I suggest heading back a few steps and looking at how it works on the thread of Root access obtained by Bin4ry.
The Baseband has to match the build and that's about it. There have been lot's of cases of people getting them mixed up by not doing full system restores, which unless you do this, leaves the Baseband in place and flashes newer build files over the top and they conflict. - match - not - Got me yesterday with TripNRaveRS Gingerbread 2.3.1 v1.1 (now obsoleted to 1.3) and allowing the 2.1.A.0.435 to be flashed by SE Update when things got screwy and I needed to Flash back - out... there was no way of doing this so what happened was I became stuck without any Baseband matching 24 rom / the 2.3.1 Gingerbread rom.. in fact - it basicly forced me to eventually do a full restore just to get away from the 2.1.54 Baseband as it isn't compatible with 90% of anything made to date - lol -
Here is the architecture of the Android "Radio Layer Interface" - core Telephony provider layout and extrapolation.
