12. The method of claim 9 wherein using the first SVM learning model in the mobile phone to classify the text message comprises: parsing the text message to extract features from the text message, the extracted features being identified in the first SVM learning model; consulting the first SVM learning model for score values of the extracted features; and comparing the score values to the threshold included in the first SVM learning model.
