2. If you equip the pedometer, then equip that... uhh... love/friendship rating bracelet thingy, it still shows you steps
3. When I went to a festival (the cooking festival to be more specific) with the friendship rating thing equipped and talked with either the mayor (Thomas dude or... whatever his name is in the game) or the Gourmet (I can't remember, I'm pretty sure it was the Gourmet), then left (and then teleported me back home to cook or whatever), it showed the thing that would show if you talk to people with it equipped
^^^ That one first happened without me noticing, so that's why there isn't much info about it
I don't know if anyone has found these glitches already...
