Help Needed

I really need some help..i'm stuck here " You now need to Disable CommCenter on your iPhone.

To do this open /System/Library/LaunchDaemons/com.apple.CommCenter.plist on your iPhone and select 'Edit with Transmit' from the 'File' menu (or right click)."

how can i do this?

You can just use this command

launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist

Or copy the file onto your desktop, edit it on the desktop using notepad and then copy it back to the iphone.

and this works without problems?
