undo DFU fix - ?

[frrok]

Weird Question, I ran the applescript that enables DFU mode to jailbreak iPhones on my 20inch intel-mac, thinking that I would eventually jailbreak my new 3G. But I havent done it yet. Now I just found out that the new quicktime updates messes up your computer if you ran this script. How do I undo the script so I can update quicktime? I am not planning on jailbreaking anytime soon. I will but not now. I'd rather have the quicktime update for now.
heres is the link to the instructions on how to run that script:

very good question. I was wondering what the effects of doing this and not just buying a USB hub would be. If I find an answer I'll post it here a.s.a.p

Copy the backup files(it should be under Backup_IOUSBFamily_kext_10_5_6 on your desktop)to where the automator script was.Then Install_IOUSBFamily_kext_10_5_5 on your desktop.Run the automator script again.It will copy those "original" files to the right location.Then change the permissions correctly and reboot your machine.
*If you had trouble with the automator script,you can ssh into your phone:
sudo rm -R /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/AppleUSBHub.kext
Enter your administrator password here

sudo rm -R /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/IOUSBCompositeDriver.kext
sudo cp -R $HOME/Desktop/Backup_IOUSBFamily_kext_10_5_6/AppleUSBHub.kext /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/
sudo cp -R $HOME/Desktop/Backup_IOUSBFamily_kext_10_5_6/IOUSBCompositeDriver.kext /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/
sudo chown -R root:wheel /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/AppleUSBHub.kext
sudo chmod -R 755 /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/AppleUSBHub.kext
sudo chown -R root:wheel /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/IOUSBCompositeDriver.kext
sudo chmod -R 755 /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/IOUSBCompositeDriver.kext
sudo rm -r /System/Library/Extensions.mkextprivileges
sudo touch /System/Library/Extensions
sudo reboot

Your machine will reboot after prompting to update boot caches and the files should be back to the standard 10.5.6 ones.
In case your Mac is not recognizing your iPhone in DFU mode,use a USB hub in-between the DFU device and the Mac and insert/reinsert the iPhone’s usb cable.

I actually downloaded the 10.5.6 update again and then updated quicktime and everything worked fine.

Out of interest, I ran Disk Utility the other day (I do every so often) and it came up with a load of permission fixes headed IOUSB.

Haven't tried putting my iPhone in DFU mode since but I did wonder if this had "over-ruled" the DFU fix.
