Looks like Apple has decided to do something about the find my iPhone problem. Given its not much, but they have done something.
Yesterday Apple released a tool that you can put in the imei or serial number of the device and find out if find my iPhone is on. As most buyers of idevices know there is quite a few websites that will do this for free. But from personal experience with them. We found that they are not always 100% accurate.
So if your going to buy a used idevice make sure you check that imei or serial now. Below is a link to Apple’s imei checker.
