iTunes 10.5 hangs during iPhone 4 sync

having a similar issue. updated to itunes 10.5, and on start up i get an error message that reads "iTunes requires a newer version of Apple Mobile Devie Support. Please uninstall both Apple Mobile Device Support and iTunes then install iTunes again." i did that and still get the same message. any thoughts?

I have been having the same issue and have tried the following:

1) Deleted Backup from C Drive in case it was corrupted

2) Restarted several times

3) deleted Itunes the correct way meaning, Itunes, Quicktime, Mobile Support, Update manager, Bonjour and Application, etc. and reinstalled Itunes...did this 2x and still having issues

4) let it Back up for 4 hours...still nothing

In windows 7, click on your start menu, go to accessories, right click on the command prompt icon and choose "run as administrator". Once it opens, type in the following command...

netsh winsock reset

hit enter and it should say something like winsock reset successful now reboot your computer.

Finnaly made it home to try it myself and it is working great. Thanks japiohelp. You are today's apple hero!

Hi, Does anybody know what can fix this issue in XP? I have tried all the steps to uninstall all items and reinstall 3 times now and still freezes on backup and apple mobile devise is still taking 50% of the CPU.

So frustrating. I just want to get my phone ready for upgrade tomorrow.

I've two Windows 7 64 bit desktops.

On the one I've always used which has all my backups, apps, music etc etc I'm having the same problem and I've tried everything including above suggestion, removing and reinstalling, New download, stopping processes using MSCONFIG and Autoruns all to no avail.

On the scond PC it's all working perfectly but I've no backups, apps, data, music or data.

Not happy.

It worked for me too. I am using Windows Vista.

Thanks a lot !!!!!!!!!!!!!

The one difference between my two 64 bit PCs is that the one with no problems has not had Tuesdays Microsft updates installed whereas the problem one has.

Perhaps the .Net updates or one of the others is blocking access to the iTunes store?

That's really perfect. Thank you

I've tried it three times to no avail but I'm pleased its helped some members.

I can confirm that entering netsh winsock reset in the command prompt in windows xp also worked. Now done on 2 machines & both successful. Thanks for the fix. Saved me pulling my hair out.

Any suggestions as I'm really desperate please?
