I have a brand new iphone4. The first time I plugged it in tothe computer via cable it synced fine. I was able to put in music etc.Nowthough, it recognizes the device since it shows it under Devices, but I cantadd anything to it. It just opens a screen saying “set up your iphone, thiscomputer has previously been synced with an iphone or another ios device”. WhenI try to restore from the backup, it gives me an error message “itunes couldnot restore the iphone because a session could not be started with the iphone”.I also got someother weird x08……. Message which I cant remember now. Only whenI actually set up another iphone does star tto sync, but then it comes up with an error saying "this iphone could not be synced. an internal device error occurd". When I press ok it says "the required file cannot be found". Help? BTW, when I do a reset on the iphone (erase all cnotent and settings) I am once again able to put stuff onthe Ipod and it will sync ok the first time. Then it messes up again by giving me some error during syncing the 2nd time around and then it wont do it anymore. I tried this a few times to see if I am doing something incorrectly but every time same thing happens. I have itunes 10.3.0.54. ios 4.3.3 on my iphone.
