Re: ARLA/CLUSTER: Vídeo demonstra como aceder a um vulgar telemóvel através da rede GSM

[Carlos Pinheiro]

Caro João Costa,

Acho que o título não está muito correcto, pois lendo o artigo conclui-se
que a ideia é aceder aos dados de um PC através de um simples telemóvel e
não " aceder a um vulgar telemóvel através da rede GSM ".
