Last night, someone stole my daughter's iphone 4. We tracked it from a shopping center to another store using "Find my iphone" app. Then, when my daughter went into the store and told the few people in there that she knew the phone was there - "surprisingly" we lost the tracking signal because they must have powered the phone off when they knew it was being tracked. Some of the people left the store abruptly and we didn't recover the phone. So, my question is why doesn't Apple or someone else give you the option of remotely turning the device back on? If I could just turn it on, we would be able to locate it right now and this would probably help thousands of other people find their phones. This seems like such a simple solution and I can't find anyone that offers this service. Can anyone offer any advice?
Simple answer is that once the phone is turned off, it is fully powered down and the wifi and cellular radios are off. There is no way to send any kind of signal to it to turn on since it is not listening for any signal of any kind - it is fully and truly powered off.
The only way to do what you want would be to redesign the phone to never power off and always be monitoring, at least periodically, the cellular and/or wifi radios.
And even so, by now the thief has had ample time to simple restore the device as new, and all your info, including the settings in iCloud for find my iphone (indeed the iCloud account itself) have been wiped from the device.
