This is the guide that I used to install iPHUC:

After you use iActivator to jailbreak the phone, start with step 14 on the ringtone guide. (the other steps are to jailbreak on an intel mac)
at first I could not get it to work, but after careful review it was my error. my suggestion is to read all the directions first then try it because if you miss a step it doesn't work, I thought that I was doing everything right, but I wasn't. I bet most people that don't get it right probably do the same. In the iPHUC guide there is an important step in red at the bottom, that's what I was doing wrong. after you run iPHUC type "ls" in terminal to check your work, post it and somebody will tell you if it looks right. By the way I see a new iPHUC PPC download, I used an older iPHUC, so I don't know if it's the same file or a different. hope that answers some of your questions, post em up if you have more.
