Here are the original build.prop values for Canadian Galaxy S3s in case anyone needs them.
Telus, Rogers, Bell
I wasn't able to verify but Virgin Mobile and Sasktel most likely have the same values as Bell, Telus, and Rogers.
And Videotron and Mobilicity likely the same values as Wind Mobile.
Samsung Galaxy SIII < HTC Desire HD < HTC Touch Pro 2 < LG 490
