if the rsn is lost then how can we retrieve it?because reliance keeks only the present rsn and rsn previous to that.so anyway of retrieving the rsn from a cell.actually i got a nokia 2255 who's rsn is blocked.what happened is my friend was using it and later he got the no transferred to a sim..but the reliance personnel didn release the rsn and now even they don have the rsn.so the handset's lying dead.any way of reviving it?
rsn = reliance serial number
