iPhone sync problems? Try this

Sometimes the weirdest, most unlikely solution can solve the most vexing issue

I spent the better part of yesterday trying to resolve a problem with my iPhone: after migrating iTunes to Windows 7, it wouldn't sync properly.

Specifically, iTunes would conk out about three-quarters of the way into backing up the iPhone. I literally waited hours, hoping it would eventually finish the process, but no luck.

I won't bore you with the gory details, other than to say I did a lot of resetting, restoring, waiting around, cursing, and hair-pulling, all to no avail. (I hope it comforts you to know that even we so-called experts run into crazy glitches like this.)

One thing I tried was booting my Vista partition and syncing the iPhone there. And guess what? It worked! That, my friends, is exactly why I'm a proponent of making a gradual migration to Windows 7: If something doesn't work right, you have a fallback.

Still, I needed my iPhone to sync in Windows 7. But no amount of troubleshooting would solve the problem.

Then, I tried something totally crazy: I plugged the sync cable into a different USB port. And believe it or not, that did the trick. The iPhone zipped through the backup process and was back to normal. Hallelujah.

I can't say this will solve whatever sync problems you might be experiencing, but it's definitely worth a try. (Just make sure you're not in the middle of syncing when you unplug the cable.)

jammed iphone

I was trying to download music to my iphone and it is now jammed. Nothing I do seems to make any difference. It thinks it is still attached to the pc. I can't get it to do anything. Please help, what do I do.

After months of perfect behaviour syncing my new I Phone with my computer, all of a sudden it will no longer sync contacts or calender. One and half hours on phone with Apple Call Centre did not resolve anything. Have tried all the recommended fixes, to no avail. Can anyone help me?

After months of perfect behaviour, this morning for no apparent reason my iphone will not sync with my PC. It connects and says 'sync in progress' but then a strange message 'unable to load dataclass info from Sync Services. Pls reconnect or try again later' appears. I have done both these things but no joy. It just sits at 'backing up iphone' fpr hours with no resolution and itunes freezes. It is asking me to enter a password for Sync Services and strange extras are appearing e.g. Dana someones library is listed under 'Shared' (although no files), and a file called 'dl mbpro' although again no files.

Sounds viral but if anyone else has advice it would be much appreciated.
