My 2-year old iPhone 5 has come-up with new problems. Suddenly,using Contacts, important stored names with phone numbers are deleted. Family members, friends, doctors, etc. all gone, including their addresses. What's strange is that stored names without phone numbers, just e-mail addresses, remain. What is happening? Also, when searching through my mail, suddenly the screen returns to the Homepage and anything I am in the middle of, gets lost. I used to be a big fan of iPhones, but no more! Trying to re-boot is not helpful either. Any suggestions. I am ready to get an LG phone.
