Hey all,i know it's old thread but it's sticky and i just wanted to share what i learned recently.
I have no iphone or any apple device for that matter,anyways apple has an option to pinpoint exact location of any of their device,i.e.if your iphone #4 gets stolen you can ask from apple to locate it ,or ,if it's in use by someone else to shut the device down,and they can see where that device has been moving,
reading this thread i learned that it even saves picture locations too...oh well,to each his own,but remember-newer the technology =easyer to get watched over- big brother is always watching

Cheers THH
