Iphone Restoring Issue

I recently tried to unlock my iphone (not 3G) so that it could use any sim unfortunatly the iphone was running the 2.0.2 software and therefore screwed up and i therefore cancelled it during the process using ziphone since then my iphone has been stuck in recovery mode and whenever i try to restore it it fails to do so and it says ipod error 6 and sometimes 2001, 2005 and 9 but most of the time its 6. I have tried manually reseting and many other things is there anything I can do. Please please please help i am so desperate...

first don't use Ziphone. Put the phone into DFU mode and then restore.
DFU mode is different than recovery mode.

Press and hold the Home button and the Sleep/Wake button at the same time.

After exactly 10 seconds release the Sleep/Wake button. Continue holding the home button until you iTunes pops up a message telling you that it has detected an iPhone in recovery mode.

The iPhone screen should remain black.

This could take several tries to get the timing right. Good Luck
