Backing up PRL Files

[ChaosTheory]

Finally! I talked to someone at Nex-tech (my provider), and found out that the only things they had to add to my phone when I did a hard reset is the PRL (Preferred Roaming List). I asked if there was a way I could get a copy of that, but she said that they can only do it at their main office and I would have to take it up there. That being said I am sure someone here knows how I can get around that, either by pulling it off my phone or something (or at least I hope so ). I would really like to do some major tweaking on my phone, just wary of doing so if I have to take it in everytime I hard reset.

Also, apparently Nex-tech does not support MMS messages on smartphones, the lady I talked to said it was due to their ROM. I didn't think to ask, but does a phone company have a ROM that distributes phone calls, SMS, MMS, etc? Or is she talking about the ROM on my phone? (Honestly not real clear what ROM in the case of smartphones and cell companies refers to).

Based on this new information does anyone think I will be able to flash one of the many awesome sounding ROMs on here and somehow update the PRL? With the tech support comment about the ROM, is it likely the ROMS on here will cause other problems? Is there any hope, or am I stuck to manually editing?

Thanks!
