I got one original 3.0.0 from local store and one from the onsale makeup sale preinstalled with 3.0.2. Does anyone have used both models and have noticed anything different such as built quality and so on? I heard rumor that the 3.0.2 models from onsale are built with worse quality but I'm not sure if it's true. Basically I'm trying to sell one, so I will keep the 3.0.2 one if nothing is different except the OS version. THX.
