Preferred mode bitmask. This is actually 4 byte-sized bitmasks with different priority values, in which the byte number from LSB to MSB give the priority.
|MSB| | |LSB
value: |00 |00 |00 |00 byte #: |3 |2 |1 |0
Higher byte order give higher priority. Thus, a value of 0x0000000f represents a preferred mode of GSM, WCDMA, CDMA, and EvDo in which all are equally preferable, whereas 0x00000201 represents a mode with GSM and WCDMA, in which WCDMA is preferred over GSM
