Here is more to try later.

1) Do a restore again to the phone till it reboots, but this time on first boot before it has a chance to do anything (after restore), put the phone into DFU immediately and try to jailbreak with redsn0w, I'd do the 3.1.3 firmware restore then use the 3.1.2 ISPW in redsn0w like earlier

2) keep playing with holding home + Power for 10 seconds then letting go then trying again, this has been known to kick the phone one.

3) upgarde to the newest possible firmware and try doing #2 above.

4) try a totally different USB cable.

let me know if any of that worked, ill keep looking
