Found something, not sure if you've seen it already : http://forum.xda-developers.com/show....php?t=1077168
This bit is especially interesting :
"*If your having problems after the radio flash......go to dialer:
Type in *#*#72786#*#*, put your msl in, and let it re-provision"
This is exhausting. I really appreciate all your guys' help though. Thanks so much.
