Propriedades do sistema com MIDP

Olá! este breve post é simplesmente para mostrar um documento que a Nokia diponibilizou, apresentando funções que enumeram as propriedades do sistema que podem ser recuperadas usando o método System.getProperty().
O pacote também inclui uma documentação e um pequeno MIDlet para verificação das propriedades do sistema afim de saber o que o dispositivo suporta.

Seguem as Classes
