My current phone (S4) is broken and a friend has lent me their old iPhone 4. I was told by another friend that when they lent their old phone to their sister in law, they started getting every photo taken with the old phone and contact numbers etc.... So questions: How can I configure the phone so it doesn't disturb my friend? If anyone has specific step by step guide available on the net or clear instructions? HELP! I dont have a phone at the moment.....my Samsung S4 turns on sometimes but the back has to be off and I can't take it out of the house! I need to sort the iPhone 4 out! Thanks!
