I have been using an unlocked iPhone 1.1.4 for over15 months which was unlocked using Ziphone. Today I accidentally restored the iPhone to original factory settings. When I tried to do the unlocking again using Ziphone, it got stuck in the middle of the process and I had to stop the process. I m getting an error message - "IOIpodUSBDevice::startIpodStack can't start! Need configuration" . Also iTunes no longer recognizes my iPhone. Somebody please help me get me back my iPhone.
