Cell phone camera and messaging capabilities are apparently being used to cheat on tests. Students snap photographs of questions and send them to confederates who SMS back the answers. In California (where this behavior was recently reported), schools are apparently not allowed to relieve students of their phones, so this form of cheating is difficult to prevent.
On a more ethical note, camera phones will enable a whole new class of product support in which photographs (and eventually video) will be used to provide much of the needed context for problem solving. (Imagine fixing your car with the help of a master mechanic who can see exactly what you're doing as he talks you through a procedure.) Today's phone-based cheating is done on an ad-hoc, individual basis--but it won't be long before commercial businesses built around the concept arrive. The same people who sell term papers will likely add online test support to their service offering. Of course, it'll be important to spin it as something other than "cheating"--my bet is that the various Web directories will list it under "Just-in-Time Test Prep Services."
