An extremely useful introduction to the subject of mobile learning technologies (I expect that the subject of mobile learning, which was in fashion about three years ago, will become the new "hot" domain of learning development. And it should. I've encountered some criticism of mobile learning as limited (largely due to screen sizes of phones and other devices) in application. However, whenever a tool has wide adoption, new uses of the existing tool have a high chance of success. There may be better avenues for learning...but the dominance of mobile phones will make them a seamless learning tool for many) - Literature Review in Mobile Technologies and Learning (via Smartmobs): "Newer developments in mobile phone technology are also beginning to offer the potential for rich multimedia experiences and for location-specific resources.
The challenge for educators and designers, however, is one of understanding and exploring how best we might use these resources to support learning. That we need to do this is clear – how much sense does it make to continue to exclude from schools, powerful technologies that are seen as a normal part of everyday life? At the present time, however, the models for using and developing mobile applications for learning are somewhat lacking."
