Pre-ported number returning after ROM update

[The Sapient]

I've updated the ROM on my phone to Vito's black pill, and the ROM on my wife's to the latest official Rom. On both phones, Settings-->Phone show the phone numbers that came with the phones prior to porting other numbers onto them. It was easy enough to change the Voice Mail numbers to the ported numbers, and I don't have problems making or receiving calls, but I'd like the phone to show the correct number regardless.

Any idea on how I can fix this?

You will need to get the MSL code for each phone, then go into EPST settings and edit the MDN and MSID. Get the proper MSID and MDN numbers from your carrier's tech support, as you have already flashed the ROMs and overwritten those numbers.

Go to the first post in this thread:
An Easy Guide to Upgrading

If you are on Verizon, your MSL is 000000; otherwise, perform Step 2 under Retrieve Provisioning Data:
of that post to obtain your MSL (or you might be able to get the MSL from tech support also). Then, no matter what carrier you have, perform steps 8 and 9 under Verify Provisioning Data: to update the data.
