Exclamation ?change phones carrier id in the low level system?

Ive probably asked this question 10 times, but never got an answer,,, and now I know why,, I wasnt asking the right question...
at first I didnt know exactly what I needed to know so my questions were very vague...

but after a lot of research I think I know what I need...

I am with alltel,, and with my original ppc-6800 I was able to flash the unofficial sprint release and use either dcd or nuerom etc, and all was well,, so when the official release came out, I flashed my phone with it, but my puter bluescreened halfway through basically giving me a paperweight,,,

I got another new 6800 from alltel, but this time I decided to put it in the box and stick it in the closet, because at the wireless store I work at, I had a brand new mogul that I was going to set up on the cricket network,, so I decided to take this one and use it instead,, so that way if I screw this one up I always have my original...

Here is where the problem inlies...

This new mogul is from qwest...

I loaded oli 2.40 then mtty'd to the phone, and supercid the phone, loaded the official release, at the setup screen i placed into bootloader, flashed one of many roms that i tried, and the phone functions perfect,
except the da** roaming indicator is on....
I ran ##33284 and checked I am on the correct sid and nid, I am authenticated under hdr,..
so unknowing of why this would do this,,, I used mtty to change the cid to allte001, downgraded back to the official alltel wm6 factory rom,,, just to see what was up...

even with the stock alltel radio/rom it was roaming,,, and after flashing to the original alltel radio/rom, qwest sh** still kept popping up in epst.

Now after quite a bit of reading, I have found that phones are programmed on their lower level system with carrier id,,, basically like the bios on a computer... and no matter what rom/radio you have on the phone, this information stays intact... thus this qwest phone will always think its supposed to be on a qwest network no matter what...

So the phone polls a tower, it receives the carrier id from the system it is programmed to be on from epst, then matches it against the carrier id stored in the lower level, if its a match then voila, if not the ril comes on... even though its not roaming...

has anyone came accross a way to get to this programming?

I found out that the phone does have a lower level programming mode,, called download mode... if you hook yours up to qpst, then open the filesystem backup utillity and click on ce filesystem, and try to do a dump of the phone,, it takes the phone out of diagmode/dmrouter and blacks it out and puts it into download mode,,, but this new mode requires 2 different data interface drivers that I cant find,,,

I didnt know if maybe the drivers could be found, that we could possibly do an entire dump of the phone, then decompile and find the original carrier id, change it , then restore to the phone...???

please feel free to chime in,,,
