Hi !
I just got my first I-Opener. It's a V4. I'm using Badflash.com BIOS. Everything is installed, all drivers are loaded, including the PCI sound one. I have even tried the callwaiting external 56k modem driver from ActionTec.
My modem is always giving me a "No Dialtone" error.
If you have a modem you would be willing to sell me, please let me know. I'm building this I-Opener as an Internet Station for a friend... Without the modem, it's basically useless. 
Thanks !!!!!!
