I really hope someone can help as I have been trying to fix this all day. I am trying to get the iCloud back up and the itunes wifi sync to work on my iPad2. I have ticked the necessary boxes in itunes, sync'd the phone and then attached the power lead. But the sync button stays grey out. In relation to the icloud back up, when i press the Back Up Now, all I get is an error message, there was a problem completeing the back up. Please try again later. Now I have read this MIGHT be down to Apples servers being busy, but when I do the same on my wifes iPhone, to back it up, it starts at least and does'nt return an error message. Please help??
