So I have read on several different forums about signal issues and the PRL on the phone. I initially tried the simcard pull trick because *228 has been known to fry simcards, but it never updated the PRL, it stayed at 15109. After more research I found that you can save *22899 as a contact and then dial the number and that will update the PRL. Well needless to say I tried it and actually it worked. My PRL is now at 52870 and my signal is much better. Might be a good option if even after the updated radios your still having signal issues.
