Thank you totallyagit, I'm done with the "erase" process, but now I'm having the same problem only in my computer. When I connect the iphone on my laptop it shows the error "iTunes error 0xE8000012", but in other computers it works. I've tried many options of apple support, but nothing seems to work until now. Any idea ?
Thanx for the answers again.
Do you have something called wi-fi sync installed on both your iphone and pc? If so,uninstall them both.This was posted by someone else on another forum.
"Well, I finally solved the problem without any help from Apple.
I found in one thread in a different forum that the problem could be related to some "Lockdown" folder on the iDevice. I tried various suggestions, deleting, or changing permissions on a couple of such folders on my iPad, but nothing helped. I have also tried two different computers, even a Macbook Air, without success.
Then I found the folder C:\ProgramData\Apple\Lockdown. It contains SystemConfiguration.plist and <deviceid>.plist for all synced devices. I found that the .plist file for the failing iPad was missing on the computer where I am now located (traveling on vacation), while it exists on my computer back home (halfway around the world). So I copied the missing <deviceid>.plist file from my remote computer, which I fortunately left running and have full access to via Hamachi.
Voila, sync now works without any problems on the previously failing iPad 3
Of course, this fix only works if you have access to some computer where sync has previously worked at least once. I think the only other solution is to Erase All Content and Setting and restore from backup which now hopefully(!) works."
I registered an account here just to post this and let everyone know that reads this that it does work. I read this and then went to my desktop and copied my plist from there to my laptop and now my iPhone sync with itunes again. I tried deleting and reinstalling itunes but that didnt work but coping the udid plist works perfectly.
