I found that Gemalto sell excellent development kits that allow developers to develop applications that run on SIM cards. These applications can be downloaded on the SIM cards and can perform powerful functions like intercept primitive radio messages and send data to other servers. Amazing stuff! Because these applications reside on the SIM card, they can run on any phone. No more special operating systems, and applications build for the Blackberry or iPhone only. The same application runs on all phones. Now any-one can build an application and download it on their SIM card.
Only problem is the cost ot the development software. Why do Gemalto sell the software? What are they thinking? Surely by distributing the software for free, more people would see the benefit and utility of the SIM card?
