Following a recent update to its MobileMe service, Apple has released Find My iPhone for iPhone, iPod touch and iPad devices. A native app for the web-based service, Find My iPhone can be installed on any device running iOS 3.1.3 or later and assists users in locating another lost or missing iPhone, iPod touch or iPad that is using the MobileMe service. Users simply sign in with the MobileMe member name associated with the missing device and the Find My iPhone app provides an integrated map to show where the lost device last reported its location. Users can then display a message and/or play a sound on the remote device, remotely lock the device with a passcode or wipe the device completely in the same way as through the MobileMe web-based Find My iPhone service. Note that the Find My iPhone service must already have been enabled on the missing device in order for the app to locate it. Find My iPhone is a universal app that runs natively on iPhone, iPod touch and iPad devices and is a free download from the App Store, although a $99/year MobileMe subscription is required to use the Find My iPhone service.
