So I was reading how Find my Iphone is now free and can be installed on 4.2.1 devices. Also I was reading tutorials on how you can make it work on non supported devices like the 3G and 3GS or lower firmwares. Anyways I got a i4 running 4.1. My friend has a i4 running 4.2.1. I created the account on his iPhone. But what exactly is the point if I create the account on his iphone as now I can track his iPhone.. completely useless.. How the **** does that help me track my iPhone? All these guides stating how to get it for non support devices/firmwares.. what's all this jazz about? Can someone explain this to me? Cause to my understanding dont you need that "Enable Find my Iphone" option in order for it to track your device?? Thanks!
