Try to flash back to stock rom 1st and use it to make a couple calls if that cures it then it might have been a bad flash I have had this happen to me even after a couple days of working just fine. I flash back stock rom and used it and then go back to what I had and it seemed to cure my problem and yes also update your prl. Since I re-flashed back to custom rom and did update to the PRL I have not had the problem and been using it over a couple weeks without one dropped call and even in an area where it is known to be weak for signal anyway.
