0.8.0-rc.3 - bug?

This works in 0.8.0-rc.1

void cloud_set_apn(void){
   //Check that the modem is on and ready for AT commands
   DEBUG("Checking if modem is on");
   int response =  Cellular.command(5000, "AT\r\n");
   while( response != RESP_OK ){
  DEBUG("Modem not responding... must not be on!");
  response =  Cellular.command(5000, "AT\r\n");

in 0.8.0-rc.3 it is stuck in the loop forever.

Let me ping someone that might be able to help, @rickkas7 or @ParticleD are you able to assist?
