thank you for the input
I turned for help to the page plus flashing thread I used initially to flash this phone. I need to find out why the 16 digit password to unlock my phone does not work anymore. The 16 digit password is the same thing as the SPC MSL, as in it unlocks the phone so you can edit the CDMA settings.
Im pretty convinced that either the data or evdo settings got changed, or I need to update the PRL again, like you said.
Flashing the ROM changed one of those settings. We will fix this together XDA !
