Help me unlock v1 iphone firmware 2.0

[rivet]

Hello,

I just get my locked iphone with firmware 2.0 in the post office. I am reading the iclarified page about the instructions of unlocking iphone 2.0.
http://www.iclarified.com/entry/index.php?enid=1572

I have a couple of questions before I begin to unlock. 1. Where can I find these BL-39.bin and BL-46.bin files. 2. I can't find firmware update files on apple.ca website, do I need to connect my iphone to the computer and let it download the firmware? 3. When should I connect my iphone to my PC, should I done it after the custom firmware is built, before step fifteen in the guide? Thanks,

Anything I need to particularly paying attention when I am doing the unlock? I really don't want to mess it up.

Thanks,
rivet
