Hey Melott,
You're not going to like this, but I have one of the 3000's that softkicked, and had 3.1 softkick for the 3000. Mention, had. Unfortunately, as I understood you had to have physical 3.1 roms to run OS3.9 I switched to physical roms and no longer have the 3.1 softkick rom. That said, at least you know you can switch to a 3.1 rom chip set, but of course, the ability to softboot into old versions of the OS is lost.
