Good sticky thread
There is plenty of info ALL over the web to prevent this from happening.
On one hand I feel somewhat sad for these guys and on the other I don't.
PLEASE READ and inform yourself on what you are about to do to your phone. An hour or two of thread travel can relieve you from alot of pain and suffering.
Also don't be afraid to ask. I've noticed that most of the "HELP MY PHONE IS BRICKED" threads have the OP with a count of 2 or 3 total posts. Just ask if you're not sure about something.
I know that not everyone will help you out sometimes, but maybe that one person will.
