Can someone explain the firmware image name scheme? Is the following file from Navifirm the generic file for 16gb N9s?

DFL61_HARMATTAN_40.2012.21-3_PR_LEGACY_001-OEM1-958_ARM.bin

Maybe we don't know yet as there are only a handful of images on navifirm? Most of the file name is self explanatory but it's 'PR_LEGACY_001-OEM1-958' I don't understand.

Thanks, Stuart

(not so much) later… an answer to my own question, sorry.

There's a post on Nokia Developer with an explanation of version naming. You need to register to see it I think.
