Is it really true that you can't downgrade the baseband from 06.15 back to a normal baseband? I find this hard to believe since it is a software thing. All software things are reversable.
I got a 3GS that someone did this too and I'd like to downgrade the baseband. Any thoughts?

It is irreversible as of right now. Sheriff Hashim attempted to downgrade the base band and the result was that the phone was bricked. If you look at his twitter time line you can see the results. The problem is that it is not just software it is also hard ware. Apple has altered the the code and the hardware so that it can not be down graded. The only hope would be for Apple to put out a baseband that had a higher version # so to say and the chances of that happening after the whole thing with the iPad baseband is highly unlikely.

The only time it was ever mentioned as a possibility was on the 2&3G using Fuzzyband and even then I never heard of many people having luck with it. I tried it more than once and it didn't do squat. The baseband is the modem driver I think the baseband is not loaded like the firmware I think it is flashed and then it is not altered again unless it's for a newer version. Just remember on the 2G the very first JBs/Unlocks could only be done through hardware, swapping out the chips Them were the days!!!

I just put 6.15 on a 3GS full well knowing it can't be undone and never taken to apple as they won't help you only reason you should ever do this to my knowlege is to unlock it if the previous baseband is unlockable I did this so it could use tmobile also FYI you can never use restore option in iTunes with original software it will not work you have to use dfu only mode and load custom firmware thru iTunes I wouldn't recommend this unless you know what your doing and ok to live with it. I know the question was how to undo it but wanted to share knowlege hoping it could help someone everything I read also it can't be undone

The only reason to use it is if you absolutely must have an unlock; if you don't need that it offers no positives, only negatives.
