You Know The Keys Lock, Right?

When I first saw the blackberry ad about "butt dialing" I thought it was pretty funny, but also a little ridiculous. I mean, there is a key lock, so if the whole flip thing really necessary? And then I got called three times in 20 minutes by my husband as he was walking around the store with his phone in his pocket. Now I think the Blackberry flip phone is a genius invention for those people out there who can't quite figure out how the key lock works.
