Unknown Carrier Upgrade?

[timm9]

Hi,

I’m pretty inexperienced but trying to learn. I have also searched quite a bit but I’m not sure I found the answer(s) I’m looking for. I have the 6800 with a small carrier that does not have the ability to release ROM updates, etc. They are a great company and do not cripple any of the phones features. They purchase phone from larger carriers and are not sure where they got the 6800’s. The stock 6800 is running R 1.64.00, D 2.17, WM 6.0. My questions are as follows;

Is there a way to find out which carrier the ROM is based on by any settings, etc. in the phone to avoid upgrading to the wrong ROM?

Is there a way to activate the internal GPS antenna via cab file, or registry edit without upgrading the ROM to run stand alone GPS such as TomTom?

Did I read correctly that when upgrading the ROM there is a way interrupt the process to avoid carrier specific features from being loaded?

Any help you might be able to give would be greatly appreciated including any questions I should have asked!
