Help! iPhone won't load and is unrecognizable.

[Inverse24]

So, I got my iPhone pwned by a friend. Everything was good until I switched back to ATT. I wanted to upgrade my phone to 2.02 and while updating the process just stopped and got an error message that my iphone was not recognizable. Now, my iphone just shows Pwned! and a skull, nothing else. I tried to put my phone into recovery mode, but when i go to restore...it says the iphone could not be restored and an error (6). what do i do!?
