Implement Radio Interface Layer !!!
In Windows Mobile 6.5, this library exist, and it's very good for retreive lot of cell tower informations ( Cell ID, MNC, MCC, LAC, IMEI, IMSI ) lot of information we do not have access with Windows Phone!!
Such information could be very userful to get the location whenever the GPS doesn't work because inside a building.
Other userful app could be developed if those data would be available.
