I think most my friends who've past would have winded up in hell all but 2. If heaven had a phone, I would definitely want to call my good friend Vicky I transferred my contacts yesterday from my old phone, and it was depressing when her # came up and I can't call her
I don't think a child molester would be in Heaven, so I don't think Michael Jackson is a valid answer.
e.e This thread reminded me of The Twillight Zone. On one episode, a dead grandmother talks to a child through a toy phone.
