Five months ago, I managed to muddle my way to flashing my Rogers I-896 from stock 2.2 to FireFly 3.0 and even managed to install voodoo ext4 lagfix.
I like it, but I'm keen on trying a 2.3 rom. I think I've settled on dlev 4.2, but the GB kernal upgrade has been my hangup where I was unclear, so I've stayed with FF.
Anyways, I just wanted to say thanks for posting this.
It has helped answer a few of my questions.
EDIT: Just got me a THANKS button. I used it!
