It's easy to find your lost phone. You login to your aPhoneTracker map page. It shows the current location of your iPhone. You go pick it up!
You can find your friends and family too. Give them an iPhone as a present. When they fall in love with the iPhone they'll carry it everywhere! Then download the aPhoneTracker software to their iPhone (with their permission of course). Now you can login to their aPhoneTracker map page from any PC. You immediately see the current location of your friend and their beloved iPhone!
