I was home and couldn't find my phone. So, as I usually do, I fired up "Find my iPhone" on my iPad to play a sound on my phone (so I could find it). Anyways, I couldn't hear any sound, so I looked at the map, and my phone was a couple of blocks away. I couldn't believe it. I must have dropped it somewhere or something. As I'm watching in disbelief, the phone starts to move slowly on the map, as if someone's walking with it. I turned on "Lock my Phone" and sent a screen message with info on whom to call etc. (I also have a sticker on my phone with my contact info). Phone keeps moving until it stops moving another 3 blocks away. A total of 5 diagonal blocks from where I live. I have a friend call my number multiple times (I FaceTimed the friend via my iPad). No response. (I didn't go to where I could see the phone earlier because I don't have another cellular connected device. My iPad is wifi only, and would have lost the ability to track the phone if I went out.) I drive down to the where the phone stopped moving, and there are 2 mansions there. I am hopeful. These rich people won't keep my phone. Plus they haven't disconnected the phone by doing a hard power-off. But why aren't they answering calls? And why haven't they emailed me about it yet (my email is printed on the phone). I come back home. About 15 minutes later, I check Find my iPhone again, and astonishingly, the phone is moving back towards where I am. In fact, it is slowly moving back towards the building where I probably lost it in the first place. This building is in a college campus with wireless wifi. (This college building is about 1 block from my home and about 4 blocks from the place where I had driven to.) So I grab my iPad and set out to look for my phone. As I get close to the phone, I play a sound on it (via the iPad). I find the phone ringing in the exact same spot where I was sure I had lost it (a chair in a lobby inside a building). Through independent verification (surveillance cameras), I have been able to verify that the phone was sitting in that chair the entire time. However, for a while, Find my iPhone showed it as moving across my town, and then settling in one of two possible houses in the town. I almost knocked on each of those houses to inquire about it. If I had another cellular connected iDevice, I would have probably grabbed some person walking the road and accused him/her of having my phone. Find my iPhone was initially grossly inaccurate in judging the location of my phone. Be careful using it folks.
