I have an iPhone 5s and i recently downloaded the latest iTunes on my Mac Book Pro. The setup is almost 2GB. When i try to update the iOS, it gets to the step where it starts restoring and backing up and then suddenly pops up with an error code 3004. Is there something wrong with my iTunes? Or is it an issue with my iPhone? Does iPhone 5S support the latest update?
