Ever since I upgraded to iOS 8, my iPhone 5 has been displaying a syncing icon at the top left hand side of the phone, directly to the right of where you would see the wifi icon. Also, I've noticed that my iTunes is displaying that my phone is over capacity by 2.21 GB. When I look in Setting>General>About it states that I have 4.4 GB remaining. This is a problem because I would like to sync more music to my phone. I've just started a lifestyle change with my wife regarding our health and we've actually been sticking to it. My music is what allows me to do what I do at the gym and keep pressing on. This is why this is of such great concern for me. Until I can resolve the problem i'll downgrade back to iOS 7. Any advice in this matter would be greatly appreciated.
