When using the MATLAB Mobile app to obtain data from the phone's sensors, is this data already processed or is it completely raw?

According to this and this MATLAB example they appear to be raw values. Depending what values and hardware you are using you can make an estimate by observing gyro drift (hopefully its not corrected) or introduce noise to the accelerometer and see if the response reflects it or filters it out.
