thats more the issue i was talking about earlier- taking a long time to find towers. you might try the same thing though. you will need the MSL for the device to get into edit mode in EPST (##778# or ##778 Talk). then on the Nam Settings tab there, just remove and re-add your MSID and MDN there. not sure if those are both your phone number like Sprint is or not on vzw, might have to research that if you didnt make a note of them before flashing radio. If you need the program to get your MSL download it from the following link:
GETSPC.zip
then put both files on your device and run it- adding the HEX ESN for the device where it says Input. The output will be your MSL.
