LG VX-4400

I want to drill a hole in the back of my phone to make a strap post. I spent 10 months in Japan & phone charms are a really big thing over there. I want to be able to put my charms on my phone. I love my phone, but I'm upset that it doesn't have a strap post. (I'd actually prefer to use my Japanese phone, but I guess it can't be done) If you look at the top part of the phone on the back you can see where one would be but then there's that plastic GPS label on the back where it would come out. So could I drill a little hole right there? I have no idea where all the inner parts to the phone are & I would hate to ruin something. But I must have my strap post. I've considered switching to a Samsung for this reason, but I don't like them ...
