Hey, I'm going away for 2 weeks and a couple days. And I'm leaving my phone at home, but I got a problem! I don't wanna turn it off, or let it die because I usually only got one bar, or flat line, and E... And it's hard to get that, I have dead zones all over my house and when I lose signal it takes forever to get the messages after. Anyway, Could I leave my phone plugged in, and on, would that hurt it at all?? It's a iPhone 3G!
