A Vietnamese site named Taoviet has got hold of what looks like another “lost” next-gen iPhone prototype model from Apple. This model looks almost exactly like the one whichGizmodo got hold of earlier last month, except for the screws at the bottom, which seems to have been removed. Both iPhone 3G and iPhone 3GS had similar screws with the speaker at the bottom. Also, this model has 16GB written on the backside compared to the one whichGizmodo got which had XXGB written on the back. Are we looking at the very final pre-production model of the new iPhone? probably yes!
