iTunes 11.05 or lower is needed, or you have to use Redsn0w - both of which can be found in this thread

You have to point it to the stock firmware for your device, not whited00r Keep this on the other thread you made though please

Welcome to the forums

When you have the blank baseband, you need to restore to stock 3.1.3, as that will write in a compatible baseband (compatible with the whited00r unlocker).

After that, follow the rest of the tutorial for entering PWNED DFU mode with redsn0w 0.9.14b2 and then restore to the whited00r .ipsw.
