So I tried all the find my iPhone features today, and here's what I think: Map: It's decently accurate, even on my 2G without GPS. It's pretty quick too. Message / Sound: I can already see uses for this. But, a few problems. If the volume is turned down, the sound will be really, really quiet. Also, if you reboot the phone both of them go away. Remote Wipe: Definitely works. Anyone else have anything to share?
