Am not having much luck with my new toy. iTunes sync is giving me a lot of grief. Problems: 1.Address book sync seems to be utilising an old file list. Contacts I haven't had in my address book for years have come up on the iPhone. When I add a new contact on the Mac, then sync again, the new addresses do not show up. Any idea which file it must be using to sync from? 2. When I sync music from iTunes, it either crashes after just a few songs, or says it is syncing but after completion, there are still no songs on the iPhone. 3. About 50% of the time I plug the iPhone in using the USB cable, I get an error saying: iTunes could not connect to the iPhone "" because an unknown error occurred (0xE8000001), or the last digits are 18 or 25 I am not doing auto syncs and I do have the latest version of iTunes 7.5 (19). Any ideas?
