I just currently got a samsung u600 phone, and the store owner said it was unlocked, but I don't really know what the features are for this phone. I usually get Motorola's. This is my first Samsung.
What excatly does this unlocked Samsung have?!

Other then having other sim cards from different phone companies being able to use the phone. I know the sony ericson has stuff you can download, i.e. Torch.
