the google nexus s does not support the stk (sim toolkit). using for example a magicsim card i cannot get the application on the sim to load.
one of the most informative pages i found about this is here http://blog.nyaruka.com/androids-achilles-heal-the-sim-toolkit
is this different with the hypercard 3g? can i switch the card without accessing the app on the sim card or dial special numbers which i can't if there is no network coverage?
