Lost cell phone..

Yesterday I lost my cellphone. I have no idea how I could have lost it, since I wasn't even using it. I was only in two stores and the boyfriend's car. We couldn't have been out for more than 1/2 an hour. And then *poof* it was gone. We keep calling it, hoping someone will answer, but alas, no answer. If I have time today, maybe I'll go to the stores where I was and see if anyone's found it. But I'm not hopeful. Now I need to start thinking of either how to survive for a month without a cell phone, or to figure out how to get another cell phone.
