I can't use my iPhone until I RESTORE it. I don't have my Calendar backed up. It was in the middle of updating to the latest iTunes version when I received a call. The call was cut off, I guess when the software was ready to install on the phone. I unplugged it at exactly that time, and now nothing will happen until I RESTORE (I have the "Plug iPhone into USB port" photo on my iPhone screen, and I can't get rid of it. Is there anyway I can bypass this so I don't lose my CALENDAR entries?
