Good for them. This is a great cause, and a nice way to promote their movie.

you know, i think that this is an under-promoted activity that should be brought to light. we all want the newest and coolest phone and what do we do with the old ones? i can say for myself that i have a collection of a LOT of phones that i just don't throw out. i think that years and years ago, i had taken my old phones to the police station or something like that to recycle/donate them, but that was a long time ago and i have a nice collection now. i hope that more people realize that there's a benefit to recycling them, and maybe it just takes some celeb endorsement to get it done.

many post offices have small postage-paid envelopes to mail old electronics like digital cameras and cell phones. even places like office depot will take some old electronics, although they may charge you.
