what if any is the difference between problem solving between the resetting iPhone and reinstalling iTunes? My phone has been switching off with battery remaining . I used the apple chat and was told my battery was fine and to try doing these 2 things to sort it. I don't have access to a computer so have only been able to do the phone reset but I've read the 2 do similar things in problem solving so would it be possible that reinstalling iTunes could help? Also to reinstall iTunes would I lose everything on my phone?
