I have to agree I'm also confused about why people would want to downgrade to 4.0.1 if it were not for the older baseband? Does it downgrade baseband also for 3GS/4? How about for people with 06.15 like me? If it does then I owe you a big one lol.

Or is it the fact that with your method it is now possible to downgrade to 4.0.1 without shsh saved? But then again why?

last time I downgraded my iphone 3gs (old bootrom) from 4.2.1 to 4.0.1 my baseband did not change still 5.15.04. I'm pretty sure you can not downgrade baseband for iphone 3gs.
