What's Your Experience Using Cells in the Classroom?

I'd love to hear testimonials from anyone using cell phones in the classrooms.  I published a few lessons (bulleted below) in this post: Harnessing
the Power of Cell Phones in Class Lesson Plans

• Bring Poetry to Life with A Cell Phone and A Voki
• Using Google SMS to Enrich Social Studies Instruction
• Google Voice as a Powerful "Get to Know You" and Speaking Fluency Tool
• Energy Transfer Lab with iPhone Clock

If you'd like to test out one of these lessons, or if you're using cell phones in the classroom and have your own, please share your experience as I'd love to know and share with others in my practice, blog, and more.  I created this simple form to capture your experience using cell phones. 

Thanks in advance to anyone able to share.
