Do cell phones float?

Some of you guessed the subject of the blog I did earlier today. I found this item on the internet today that would be perfect for said person :) so that no other phones will be laid to rest in the bottom of Lake Freeman. Funeral services were held Monday evening after the tragic plop into the water. May it rest in peace...it had a very busy life.
