Steve Jobs might not think much of Google's old "don't be evil" mantra, but it's hard to fault a company for using its products' popularity for the common good. In what seems to be a spiritual successor to last year's Chrome for a Cause drive, Google is asking I/O 2011 attendees for their unwanted, unlocked Android smartphones in a campaign dubbed "Android for Good." Donated devices collected at the event will be put to use at charities in developing nations -- for instance, your old phone could save elephants from poachers, or help remote villages get healthcare. We aren't saying hording your old G1 is evil per se, but what good is it doing in your junk drawer?
