Can't Unlock Phone

I just bought a used 1st get iphone from a friend. He already had 2.0 installed on it. I'm running a PC. I new about Pwnage Project so i went over to another friends house to try to unlock 2.0 with it. However, his Mac would recognize the iphone in iTunes but not in finder or anywhere else. The iPwner couldn't find the phone, nor could ZiPhone. I got home and tried ZiPhone for windows, that found the iPhone but is stuck in the "Rebooting phone in Recovery mode..." stage. Winpwn also couldnt find the iPhone. However, ZiPhone must have partially started the installation because the iPhone is stuck in the state before it is activated. I tried to update back to 2.0 normal but iTunes wouldn't let me without activating. Any help to get my iPhone working (unlocked or not) would be very much appreciated.

EDIT: I also Tried iLiberty but the "Go For It" button was depressed/faded out, probably meaning it couldn't find the iPhone.
