That just happened to me today! The [!] Mail wouldn't stop coming, I just went to "Work" and played one round, and they stopped coming! So is this a glitch or not?? :ichigotchi:
It's definately a fake. I don't think there's ever been a touch-screen tamagotchi (Unless you count the DS Videogames) that person is also selling a Version 4 Touch-Screen (which are also fake), so that boosts the likeliness of that one being fake.
