Mobile Learning is Global: Examples of Teachers Using Cell Phones for Learning!

I have come across two examples of international teachers using cell phones for learning, one in India and one in the United Kingdom. It should not be surprising that we are seeing more examples of mobile learning globally since it has been found that

• "There are estimated to be over 3.3 billion cell phones by 2010" (globally)
  
• "Cell phone usage (over 350 million in China alone) outstrips television and internet usage in many parts of the world save radio"

India
In India Rashmi Kathuria has blogged about how she has been using cell phones with her mathematics students. She uses here Nokia phone to create mathematic video tutorials (example here). Additionally, she has her students taking pictures with their cell phones to take pictures of mathematical steps; here are a couple examples from her blog
1) Dodecaheron
2) Patonic Solids
3) Geoboard

UK
Converge Magazine had an article about a ICT technology specialist Jonathan Furness using cell phone cameras to document lab experiments (see his mobile blog here). Furness also documents other daily educational activities on his mobile blog via cell phone.
