Mobile socnets have to be so easy to use, as easy as sending an SMS message and to do that they really do (Today anyway) have to be embedded into the phone software or sim. This does cause many other problems though… not available on all networks, not available on all phones, requires updating etc. These are all similar to the problems we had years ago with desktop software, but were solved by the Internet and web based apps.

Be interesting to see how much integration with phone functions can be achieved through Android… maybe then we will be able to give access to the phones directory, sms and location based functions from a web app.
