    Hi guys. I tried changing my MAC address today at work for the 1st time in a few months, and now it won't let me do it. I would always type ifconfig en0 lladdr xx.xx.xx.xx.xx.xx and it would change with no problems. However now when I do it it spits the error stating "ifconfig: ioctl (set lladdr): Operation not permitted"

    Anyone have a clue why this is happening? Last time I was able to do it, I was running 1.1.4, but I don't think that should be the problem. Suggestions? :confused:

    I figured it out. You need to login via Terminal 1st as root, not mobile.

    Well, how exactly do you do this? How do you change from mobile to root?

    Basic linux commands from the terminal on the iPhone.

    su root
    will then prompt for password

    sometimes just 'su' on its own will work but I haven't tried it.
