iTunes 10.5 hangs during iPhone 4 sync

Just installed iTunes 10.5 and attempted to sync iPhone 4/4.3.5 several times. The process hangs while "Backing up" with the status bar right under the t in (Step 1 of 5). I've swiped the phone to cancel, which leaves iTunes continuing on as if the phone were still syncing. I used Task Manager to quit iTunes on Win Vista, restarted iTunes and attempted to sync again. Hangs in the same place. So, I restarted the computer, restarted iTunes and it's still hanging during Backing up... I am so frustrated! Help!!!

iPhone 4, iOS 4.3.3

Also worked for me. I've been trying to upgrade to iTunes 10.5 for two days now! What a relief - thanks japiohelp!

Can't thank you enough for posting this japiohelp. It worked for me, and I have already pulled my hair out.

Why is it working for some and not for others?

Am going mad here with frustration!

Having same issue. Using Windows Vista on HP Pavillion laptop. Sometimes Windows won't recognize iPhone 4 or iPad 1. Other times sync will start and iTunes locks up. Also, since upgrading to iTunes 10.5, cannot get into my 2TB Time Capsule. Have literally tried a dozen solutions (including the one listed here) with no change. Please advise.

This plus the addition of removing the free edition of spyware, then resetting my computer worked. After trying, with no success, yesterday, and it getting hung up for 3 hours, after doing these two things it took 5 minutes for back-up!

Having the same issue on Lenovo X200 running Windows 7 64-bit Professional. I've tried what seem to be the 2 main solutions, the one listed here and a complete reinstall of iTunes 10.5. Have even reinstalled 10.4.1, but to no avail.

What do you mean by "removed free edition of spyware, and reset computer"?

Oct 18, 2011 1:24 AM in response to theresafromsearcy

If you're using icloud, try turning all of your iDevices off when starting iTunes (i had 3 devices all trying to connect). This is the only thing that worked for me after doing the netsh winsock reset as recommeded above multiple times.

I wrote to the manufacurer of the network card built-in to my motherboard and received the following reply:

"Apple's latest update broke it - we're working on a fix now. I don't have an ETA yet,but it should be relatively soon."

I'm pretty sure that the type of card I have is not used by many people as it's a gaming motherboard from Gigabyte however the problem mat be occuring with other boards.

The solution is probably to add an additional network card until and if Apple does something about it.

Somehow this suggested solution did not work for me. My iTunes still hangs on synch either while copying files over in the last step or on waiting for copying files.? I am also using Windows 7 64, with new iPhone 4S 64GB and iTunes 10.5. Even tried to restore my phone to manufacturing settings, but no dice... What else can it be besides a BIG BUG in iTunes?

I found what seems to work for me so far. At least my songs are synched now. Working on the Photos and Videos next.

Check out this link to first unsynch everything first from your iTunes:

REMember to reboot after you run "netsh winsock reset" as administrator.
