Hi guys, I was hoping someone could help me out on this. I have been trying to update my iphone currently on version 2.0.2 to 2.1, and when I try to install it on itunes, it first extracts the software, then attempts to backup my iphone, but it fails, and says "Itunes could not sync ^0 To the Iphone because an unknown error occurred (-30). This also happens when I sync the device to itunes. The backup takes very long to even begin, and then the error message appears. Please give me suggestions on how to fix this problem. Thanks! BTW my iphone is not hacked or modded or unlocked. It is legit.
