No joy with that mate iphone could not be restored error 6 now stuck in recovery mode lol.
i take it you havent your shsh blobs saved , try this then before your restore to 4.1,
1.go to C:\Windows\System32\drivers\etc and put this under 74.208.10.249 gs.apple.com this in the hosts so it will look like this
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
74.208.10.249 gs.apple.com
i just want to see if this works mate , i know apple will release 4.2 fw with in the next2 weeks and so will come the new unlock for 05.14.02 baseband
im on windows 7 so had to do this in safe mode to allow me to save the host file
let me know how you have got on
