Been trying ziphone 3.0, and kept getting the hang up message. 32 gig touch running on 20" c2d white iMac, 3 gig ram, 10.5.2. Tried it a number of times, kept having to restore my touch. iLiberty worked. Kept reading about ziphone, so i thought, what the h@||, I'll try downloading it again. Downloaded and installed it, restarted my imac, and whaddya know, no hangup. I had to make sure I disconnected the touch after it rebooted, because it went through the process two or three times in a row. It appears to be syncing with itunes, no problems. I'm going to try the same with my 16 touch, which has already been jailbroken using iLiberty. Wish me luck.
