I find the Epic GPS to work very well generally, especially in custom ROMs like CM7. That said it all falls apart whn trying to use the GPS in airplane mode or when overseas (or other areas with no CDMA cellular coverage). From what I can determine the Epic 4G was not configured properly to use the GPS chip in these circumstances.
To fix this issue you need to change the GPS settings on the actual gpsOne chip. This will allow the phone to get a GPS signal when in airplane mode and/or not within a CDMA service area. The procedure is time consuming and annoying but in may experience, worth it.
