1. Do I have to launch the apps in order to use its StreetPass/SpotPass functionalities (ex. Do I have to run the Mii Channel in order to share Miis?) 2. Will Play Coins/Steps count increase even though I leave the 3DS to sleep whilst an application/game is running/game is suspended? 3. Do I have to launch StreetPass Mii Plaza everytime I go out to gather more Miis? Will it still work if StreetPass Mii Plaza is suspended (pressed Home button then put to sleep mode)? 4. Do any of you use Power-Saving mode (found in Screen Brightness options)? Opinions? 5. Is manually selecting Sleep Mode work the same as closing the DS to enter sleep mode? 6. How does SpotPass exactly work? What if it connects to hotspots that, although have no security, require internal registration? For example, I can go to a shopping mall where they have unsecured hotspots but they only ask information once you connect to that hotspot. I'm very very confused with how to exactly implement StreetPass and SpotPass. Kudos to the person who answers these clearly. To me it's quite baffling.
