i don't think i can rely on the phone powering-up by plugging it in. from my experience it doesn't always go. maybe of it's off as a result of a low battery it might turn on automatically upon being plugged in. i don't know for sure.
so thank you but i don't need an app for turning it off. I'll just wing it until the imminent end of my MeeGo career. now i just gotta decide what kinda phone to buy. I'm thinking Android or Lumia. there's probably a thread for that already.
