Ipod Touch on Thick as Thieves

I was watching the latest movie featuring Morgan Freeman and Antonio Banderas, Thick as Thieves. As the movie goes, they used this handy gadget IPOD Touch to spy on their next "prospect project".

Here are some snapshot of the movie. I know you wouldnt like me spoiling the rest of the movie. I just want to share it to you readers.

And I wonder what type application could do this. Hmmm makes me think...really?
