Is it responisve at all? Can you describe the condition it is in now? You can try to put it in DFU and try a restore in itunes. Happened to me yesterday while trying to JB my 2g touch. It was unresponsive to any button presses and looked like I bricked it. I tried to put it in DFU mode while connected to itunes and it found it right away. Did a restore and works like before.
