Where is the best place to get help for fixing an iPhone 4?

I have a friend who brought me his iPhone, and it is literally in pieces. I need a forum style website that is SUPER active with a lot of traffic to help me recover the iPhone I have here. I know there are hundreds of iPhone based forums, which is the best and most active?

I pursonally use http://www.imore.com/....imore.com

They don't only have one of the best iphone forums but they also deliever the best content as far as news goes.
