Do you know if the modem file is embedded in these firmware updates?
I am considering trying different regions to see if the ROM gives me a better signal. I am in the USA (phone not yet released here so there is no version optimized for any carrier here as yet).
The phone I got came with version I9200UBUAME5 (Trinidad and Tobago). If the modem is not included in the firmware then it is a moot point. Or if the same modem is used across all firmware versions, it, again, is a moot point and no sense in me wasting time trying. Let me know.
