Unlike most people who see signal level improve, in my case, the signal level actually decreased. I do not know what the problem was? so I also upgraded 20227 prl file and hope it will improve the signal level. After the prl file upgrade, I still get same result and sometioms I got "unable to call" error message which has never happened before.
My carrier is SPRINT and my rom is BigJ's new core 1.1r.
Any hint what's wrong in my case? or where can I download 1.27 radio so I can roll back my radio to 1.27 and compare if that will help?
Thanks.
