sync freeze problem with iphone

[victor kelly]

I have my iphone for over a month now and was able down load musice from my itunes library with no problems, however a week ago i went to update my iphone with music I had purchased from itunes and had a problem when syncing it seemed to freeze telling me it was syncing to ical, this lasted for over 20 minutes and I eventually ended the sync by having to force quit itunes. This also effected my email, safari and ichat on my Mac having to force quit them as well. I eventually got these back again via a window appearing asking did I want to save changes which I said no to. I have not synced my iphone with my Mac since in case i have the same problem again.
Any ideas what my have caused the problem and is it safe to try syncing again, Also I now cannot get wifi on the iphone (yes it's turned on) and all my email now comes through Edge.

There was a widespread sync problem over Christmas/new year that was due to one of Apple's bug reporting servers going down - iTunes was trying to contact it and couldn't, so the sync stalled. It should be working OK again now.

Thanks for that, I'll risk trying to re sync.

Here is the solution

HERE IS THE SOLUTION: What it usually is is that your have a "do you want to sync contacts?" or "do you want to sync calendars?" popup window hidden behind the iTunes window. So, minimize the iTunes window. Then accept the syncing of calendars of contacts (or other items) and the frozen synching problem goes away.
