I have lost all entries on my i-phone calendars!
I have lost all entries on my i-phone calendars. My software update won't go through supposedly because I don't have enough storage. I got rid of a lot of apps but still get the same message. I am worried! Can you help? Also, how can I get rid of my yahoo mail app. I don't use it anymore, but has no little x in the corner to activate on the main screen.
iPhone 4S, iOS 7.0.3
