My DP went out last night with friends. He was very late back so I quickly checked Find My iPhone to see if he was in his way. We both do this if either of us are later than anticipated. His location early in the evening was showing as in a town 50 miles away. He has just got a new phone. When he got back I asked him about it and he looked surprised and said he'd no idea why and had never been to that address. I checked it again this morning and his phone was showing him as at home. Can this happen with iPhone locations?
