[Problem] iPhone won't restore

hi i had a iphone on v 1.1.1 today i updated in itunes to latest version 2.1 ?? and then used the quickpwn method to unlock it.

however something has gone wrong and the phone now just has a usb --> itunes logo

itunes also comes up with an error i tried doing the reset things holding home and power button then when aple logo appears relesing the power button but does nothing..

someone said about using ilibery to do a restore but all the restore and dfu mode options are greyed out.. and now if i open quickpwn it just said u need v 2.0 or greater
i also uninstalled itunes 8 and went back to 7.5 no change

what do i do?? please help

wat is the restore screen like
like in 1.1.1 with the iphone end of the usb cable

or
like in 2.x with the computer end of the usb cable

what error do you get when restoring ...
