Well i tried to update my iPhone firmware to 2.0.1 and i got an error once i got to the restore point in iTunes. I used winpwn 2.0.0.4 and follow the tutorial to the finest detail, and once i tried to restore it i got an error, 1604 i believe, but all it said was that it found an error in the restore point. If anyone can help me with this problem it would be awesome. Thanks.
