Here in the UK, we are currently being bombarded with ads from mobile phone players like T-Mobile (in its distinctive pink livery - not a Germanic colour in my book) to pick up on 2.5G/3G picture messaging services.
Most of the ads are trying to get people into "mob" activities - suncream fights, pillow fights, frisbee throwing etc. All well and good, but not really a world changing benefit.
Anyway, reading through the venerable Big Issue recently, I came across a small clipping explaining that Junior Doctors in Wales have been using photo mobiles to take pictures of X-Rays and forward them to consultants for assistance in diagnosis. It strikes me that this is a great use of the service - it could be extended maybe to teh general public with a 999-PHOTO number where, say, if you were at the scene of a traffic accident you could post a message to this service and receive a text of instructions from a trained medical professional while the emergency services beetled over to you ("Don't take off the motorcyclist's helmet, check his/her airways are clear...")
So, I reckon a big push for the medical services industry could be on its way.
