Hi, I foolishly attempted to update my iPhone over 3G, expecting the phone to prompt me to confirm before downloading a 504MB file, as this would've caused astronomical cost to me, I turned the phone off using home+power. Phone is now stuck on repeat getting to Apple logo and powering off. I have attempted to restore the phone in normal mode, in DFU mode and am still receiving the dreaded 'the device isn't eligible for the selected build' message. I have edited my hosts file, have no firewall or antivirus running and am attempting to iOS 6 - downloaded using iTunes today. Help?!
