Advantage - Camera Phone

As usual me and sahil (who is still figuring out where his blog is) was playing with Sandeep's pager. Its quite an unusual pager b'coz of it's bright yellow color and the size, of a thumb. And it so happens that we dropped it on the POP (Plaster of Paris) casting on the ceiling which had a gap. So what do we do get it out? We tried all possible way but since the gap was small we couldn't have a look inside the casting. That's when it clicked to use the camera on our phone and figure out the exact location of the pager.
