How Would You Use A Smart Phone in the Classroom?

from Wikipedia.com

I will be buying my first smart phone on Thursday. Dr. Strange don't be too shocked but I will be getting the Droid X from Verizon. I chose this phone because I don't have 3G coverage with AT&T so the iPhone makes no sense and because the X has a very large screen. (I must be spoiled with my iPad;)

I plan on using the smart phone in my classroom and school and will soon be writing a post about how I will be using it. I would really like for a few of you to think about how you might use one in your classroom. Assume you have permission to use it from your administration and parents.
