How to Backup Provider Settings?

[drtigerlilly]

I have a ppc6700 that i've had for about 4 mths now, and i find the rom that came w/ it very buggy, i wanted to try a new rom, but am afraid of losing the provider settings.

I'm not in the US, and my provider is Centennial Dominicana, so i basically want to know is there anyway that i can backup the provider settings, i gather that this is essentially information like MSL, MSID, and MDN values as well as the PRL?

How can i back up this information so that i can put a new rom on my phone, then put the settings back in, so i don't have to go back to my provider and pay them to reprogram the phone everytime i change the rom.

Thank You in advance
