LEDs yes, screen no!-(

The Ringo screen essentially works, I can send and receive messages, display setup menu etc. But when it come to programming I can access only the backside LEDs and never the screen!-(
This is the source code generated (I followed the sample from the Circuit site) that does not change anything on the screen which stays blank. Any ideas?
#include <MAKERphone.h>

MAKERphone mp;

void setup() {
mp.begin(1);
mp.display.fillScreen(TFT_BLACK);

mp.display.println("");

}

void loop() {
mp.update();

mp.display.fillScreen(TFT_WHITE);
mp.display.setTextFont(1);
mp.display.setTextSize(1);
mp.display.setTextColor(TFT_BLACK);
mp.display.drawString(“Now it’s time to change”, 10, 32);
mp.display.setTextColor(TFT_RED);
mp.display.drawString(“colors…”, 10, 48);
mp.display.setTextFont(2);
mp.display.drawString(“And font!”, 10, 56);
mp.display.setTextSize(2);
mp.display.drawString(“And SIZE!”, 10, 70);

}
