Arriving today was the eagerly anticipated iOS 4.2.1 update, along with previously-paid Apple’s device tracking, locking, and wiping tool called Find My iPhone.
Find My iPhone is a tracking application by Apple, it runs on your iOS device and tracks the location of the device. If lost, you can login to MobileMe, see the location of the device, display a message on the device, play a sound, lock the device with a PIN and even completely wipe the data off the device.
Before now this was only available on the iPhone 4, iPod touch (fourth generation), and the iPad. Follow this easy guide to get it working on any iOS device running iOS 4.2.1. To do this you must have, or borrow a friends “2010 iOS device”, either an iPhone 4, iPod touch (fourth generation), or an iPad.
