Technology is great when it works however when it goes wrong there's hell to pay, will this technology be on all phones and what cost will the app be? boy waiting for yet another update to down load, image the screen when you have a target below a piece of junk, which item will the imaging lock on to?, at the moment by approaching an iffy signal from different angles your ears pick up and can hear a good beep above an iron growl and you decide, some you dig some you don't, EMI is a big issue on some sites how is your phone going to screen that out? I think this is a nice idea but its a long way away, and what if you need to buy a really expensive phone on an exclussive monthly cost?
