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.
