Default A question about device names in Build.prop

I've noticed that other peoples LTE Galaxy notes have different names under the build.prop files, notably that Rogers models identify as SGH-i717R while Bell Canada Models are SGH-i717M, I have also noticed that this seems to be affecting app compatibility on the marketplace and other places.

For example The King of Fighters that was released today is showing incomaptible with some peoples LTE notes on other carriers however is showing compatible with my Bell note, but on the flipside I am still having to change my build.prop when installing gameloft games to avoid incompatible messages when downloading additional game data.

Is this common with other android handsets as well? this is only my second Android phone but the first one I've been comfortable enough to mess around with root on.

EDIT: meant for this go go in general.
